How do I find the sum of these 2 waves, Asin(kx-wt) and Asin(kx+wt)? I have no clue how to add 2 sins with diffent phases. Thank you for your help!

I need some help with a problem that involves the concept of quantum superposition. Suppose you have a nucleon cluster of matter helium-3 [PNP] and you attempt to combine with antimatter deuterons [N^P^], where ^ represents antimatter. Would it be possible that the two could form wavefunctions...

Dear all, I am not sure whether I understand correctly or not. So from Peskin Schroeder’s book: \phi(x)|0>= \int{\frac{d^3 p}{(2\pi)^3}\frac{1}{2E_p}e^{-ipx}|p> formula (2.41). Interpreting this formula they say – it’s a linear superposition of single-particle states that have well...

Superposition of Time Evolutions My Pathetic Explanation: A photon can be in a superposition of states by going through a beam-splitter (thus you have interference). Yakir Aharonov says you can make an object experience a superposition of time (actually Time Evolutions, or how it ages). He...

Wave Superposition! This may be asking a bit much, but I'm really desperate and don't have a clue. It's on an exam I have very soon so I need to find out! Anyone who can answer i love you lots. Here is the (big) question: 13) in this question, you are to choose, and write about, one...

For a superposition of two since waves of equal amplitude in a dispersive media, we find that the group velocity is given exactly by v_g = \frac{\omega_2-\omega_1}{k_2-k_1} and approximately by d\omega / dk|_{k=k_0}. How do we show that this approximation holds for any type of waves...

Hey, I was recently reading "If an electron can be in 2 places at once, why can't you?" in the new Discover magazine when I came across the superposition principle ( I have heard of it before, just never really looked into it). They said that evidence of the phenomena could be found in the...

I know this question isn't supposed to be hard but I can't figure it out for the life of me. If a certain wavefunction is made by superposition of three eigenfunctions of the momentum operator (F1, F2, and F3): wavefunction=0.465F1+0.357F2+0.810F3. The eigenvalues of those eigenfunctions...

To find the force due to a system of charges, we can find the force on a charge due to the other charges and add the vectors. In this context, my school textbook says, "Superposition principle should not be regarded as obvious, or equated with the law of addition of vectors. It says two...

Hi, I'm having some difficulty getting the correct answer for a problem relating to wave superpositiong. Question: Two waves in one string are described by the wave functions y1 = 3.15 cos (3.65x - 1.40t) and y2 = 4.10 sin (5.05x - 2.20t) where y and x are in centimeters and t is in...

Ok...so I don't know how to do this problem... Two speakers are driven by the same oscillator whose frequency is 200Hz. They are located on a vertical pole a distance of 4.00 m from each other. A man walks straight toward the lower speaker in a direction perpendicular to the pole. a) How...

So if we have a particle in a one dimensional box with walls at x=0 and x=a. Now suppose one of the walls is moved in a time short compared to the natural period 2pi/w1, where (h/2pi)w1=E. If the energy of the particle is measured soon after this expansion, what value of energy is most likely to...

Imagine a number of finite universes superimposing to realize our apparent physical situation. For us, their many accessible states are expressed by the behavior of corresponding probability waves. Coexisting universes, including even those representing different physics (yet retaining a...

I am having trouble with this question. Any help would be appreciated. Q. Determine the amplitude and phase of the resultant motion when two sinusoidal motions having the same frequency and traveling in the same direction are combined, if their amplitudes are 3.0cm and 4.0cm, and they...

hello folks! this is my first post on the forums and I kick off with an interesting question... I had been coming across the principle of superposition for quite some time and to admit frankly didn't ever understood it. The most abstruse aspect is to comprehend how can to different...

how are we able to clearly distinguish two different sound waves - like when someone is talking to us while music is playing in the background... I've read it is due to the superposition principle which states that the waves combine and form a resultant wave that is the sum of the individual...

hi, i was able to get all of my homework problems except this one, i just ccan not seem to figure it out. Two identical sinusoidal waves with wavelengths of 6.00 m travel in the same direction at a speed of 2.00 m/s. The second wave originates from the same point as the first, but at a later...

A transverse wave of frequency 40 Hz propagates down a string. Two points 5 cm apart are out of phase by p/6. (a) What is the wavelength of the wave? (b) At a given point, what is the phase difference between two displacements for times 5 ms apart? (c) What is the wave velocity? for a.)...

actually I did not understand exactly this model? is it indeed crystal field theory or not? how it correlates the spin hamiltonian parameters and the structural data of the crystal?

I have read about experiments where entire atoms and even whole molecules were held in a state of quantum superposition. It wasn't until an observation was made that these molecules left their indeterminate state. If whole atoms and molecules can exist in quantum superposition, does theory...

right, um, deconstructive inteference; where does the energy go? [?]

Readers, please bare with me as I attempt to explain the reasoning of my question. Any help will be greatly appreciated. Suppose I turn on my radio. And suppose one of my favorite songs happens to be playing, and that song happens to include the tried and true guitar, bass and drum trio. My...

Yo, d00dz I'm kind of stumped on this problem on my homework: "A monochromatic beam of parallel light is incident on a hole of diameter a >> wavelength. Point P lies in the geometrical shadow region on a distant screen. Two obstacles are placed in turn over the hole. A is an opaque circle...
