Sine waves Definition and 35 Threads

I am curious to know if there is any existing topic explaining how objects break into several pieces when force is applied.

Piston displacement as a function of time produces a sine wave. I need to modify the motion so the the time the piston spends at both the bottom of the stroke and the top of the stroke are extended. The motion curve would approximate a clipped audio wave. The attached image shows three motions...

Hello everyone, I've been grappling with a concept for years, diving into internet resources and pestering professors, yet I still find myself tangled in confusion. I'm reaching out in hopes that someone here can shed light on a question that has been haunting my thoughts regarding the nature...

Light is said to consist of photons or electromagnetic waves. I'm not asking which view is correct, what conditions make one view or the other more useful, or advantages and disadvantages of each view. I am assuming the two views are compatible to the extent that the wave character of light can...

Homework Statement In a photoelectric effect experiment, a monochromatic plane wave of light falls on a metal plate. The electric field in the light wave at a point near the plate varies according to E=E_0 \cos (\omega t). This results in a saturation current of 6 μA. If instead, the light wave...

So I am just working with a synth and I am having it create a single sine wave. I am then looking at the output on a db vs frequency graph and I would expect the db to only be reading at the frequency of that sine wave, but there are readings from 20 Hz all the way to 2k Hz sometimes(althought...

Hello, I need to find out how to generate a standing sine wave, or a quarter sine wave. I had no trouble finding out how to create a full or half wave rectifier, but very little generating a quarter wave, & that info mostly dealt with sound waves. I am doing this for experimental purposes...

Can you use any trigonometric wave to describe a phenomenon between two different objects? In the sense like a line or parabola would talk about a relation between two variable thanks so much in advance

I am given three sine waves with individual frequency being 10 Hz, 50 Hz, and 100 Hz. What is the frequency of the following : y(t) = sin(2π10t) + sin(2π50t) + sin(2π100t) Is it simply 100, the LCM of all the sin waves? If not, How to calculate the frequency of y(t) ?

I understand the process of rectification but just only in theory. But I still have questions that I guess will be answered if I can experience or has experience about it (but sadly I don't have). Please kindly answer these questions: 1. Does the waveform of Vout can be considered as DC (...

I saw that somewhere and it is supposed to be something Fourier came up with but I can't find somewhere why... Please explain (with mathematical description if possible)

Can anybody out there show me how the sine wave formula y=Acos(kx - ωt + φ_{0}) or y=Acos(kx + ωt + φ_{0}) is the direct solution of the wave equation \frac{\partial^2 y}{\partial t^2} = v^2 \frac{\partial^2 y}{\partial x^2} ? I mean I looked it over on the Internet but everybody keeps...

Hi I just wanted to check my approach. I have spectrum I have peak at 10Hz another at 20Hz and a third at 30Hz. The amplitudes are 1000, 500, 250. I want to recreate the signal by summing sine waves. I assume that I will therefore take A1 = 1; A2 = 0.5; A3 = 0.25; I will then let y =...

Hi all, I understand the concept of group velocity when applied to superimposed sine waves of the same amplitude, and even when applied to wave packets (in which case you get the well-known expression ∂ω/∂k). My question is what happens when you add two sine waves of different amplitudes? So...

Hello everyone. Can someone explain the relationship between the idea of a sine wave, and the idea of a sine angle? I'm getting into trig, and I hear both terms of sin tossed around, but they seem to be completely unrelated. What does the angle of the triangle have to do with a wave? Same...

I need to add together the following sine waves and express the answer in the same form: Va = 2 sin (314.2t) + Vb = 2 sin(314.2t - 120°) Any help would be greatly appreciated.

ok I just got stuck half way into a problem, I would like it if someone explained it! Ok the question says, two identical sinusodial waves with a wavelength of 3.0 m and traveling in the same direction with a v of 2m/s. Starting from the same point, just the second waves starts later. and the...

Is it possible for an Arduino to produce a sine wave to a piezoelectric buzzer?

Like the title says, I'm curious why sine waves are often referred to as "natural" or "pure" oscillations. Why not some other oscillating function? As an example of the type of idea I'm referring to, the wikipedia "Sine Wave" article says: To me, the argument that it sounds pure because...

We have met the idea that a radius of a circle rotating ANTI-CLOCKWISE can be used to draw a sine wave... I get that... it is a great idea but...why does it have to be rotating anti-clockwise. That seems so un natural to me. We were told it is a convention. Does that mean it is something...

A sine wave with a frequency of 10Hz and an amplitude of 5 units phases from zero to 2π radians in a complete cycle. How long does it take for the phase to reach a value of π radians? y(t) = A . sin (2.π.f.t + φ) 0.1 = 5 x sin (2x∏x10x time + 3.14) time = 0.038 seconds But the answer...

Hello, I am trying to work out how to determine the phase angle between two sine wave mathematically? I have setup a Matlab Simulink model and I would like to calculate the phase angle between my current and voltage (both at the same frequency) without using preprogrammed blocks, as i...

Two sine waves have equal peak to peak amplitudes 81 but are out of phase by 90 degrees. What is the peak to peak amplitude of the resultant wave. I have no idea how to start this question, could someone give me guidance?

hello i need to now if i can compare between two sine wave by pic 16f877A or pic 16f628A? that the input of pic become sine wave , can the pic read that wave or can generate it? how i can do this ? Any ideas?

Kind of new to this stuff, so hopefully you guys will bear with me. So a simple Oscillator with a Capacitor and Inductor... I understand that the energy flow causes the inductor to generate and collapse a magnetic field. I also understand that Sine waves are generated by changing the...

The 4th derivative of a sine wave is itself. This, of course, not only is a fact, but can be used to define the sine wave. My question is, are there any theories relating the abundance of sine waves in QM to the fact that the largest dimensions of space-time are together 4 dimensional? For...

Homework Statement How do i find the phase between sine waves knowing the time difference between each? http://users.bigpond.net.au/exidez/sinewave.jpg Equation for the main function is 3cos(30t - Pi/2) The smaller sine wave is of the same frequency when is settles in a steady state...

Hey friends and Sir's , I am trying to understand simple concept that why sine waves are function of (t-(x/v)) x= position in x direction v= velocity of wave t= is time at any instant although i have read many articles on it but still unable to understand , any help will be great and...

How are sine waves converted to current?? Im doing avionics in physics at the moment and we are talking about receivers... i now that the resonate oscilates at certain frequency and the antenna picks up the sine waves that are at the frequency... but how are they then turned into current...

err probably skin too many q's but anyway... what type of waves are made from naturall sources?eg then sun etc...are theren any square waves...im just wandering ifn there's any weirdness or differences when using square waves as a carrier wave in transmitting...if u know any good info sources...

I'm interested in synthesizing complex waveforms using sine waves. I know that when two sine waves which differ slightly in frequency from one another are summed, amplitude modulation (AKA "beating") with a frequency equal to the difference in frequency between the two sine waves ensues. This...

Hi folks. I'm back to make a fool of myself again. It seems that I have a proof that the 'music' of the primes is caused by the interaction of a collection of sine waves. However, I have no idea whether this is old hat, trivial or interesting. Can somebody here tell me? PS. I don't know why...

"There are two sine waves having a phase difference of 20 degrees. After one reaches its maximum value, how much time will pass until the other reaches its maximum, assuming a frequency of 60 Hz." Should I go about this by assuming... sin(120pi*t) = sin(120pi(t + x) - 20) Any hints...

Are sine waves the waves that are theoretically deemed to be the waves [naturally] emitted by all matter? Or am I getting them confused with something else?

Add the following sine waves y= Asin(wt) + Bsin(wt + x) Where w=2(pi)f and x is a phase shift I SIMPLIFIED this for my friend using rotating vectors, then i got really annoyed realizing that I didn't know how to do it the direct way (trig identities). So I've posted it here for...
