What are the properties of transverse waves?

AI Thread Summary
Transverse waves are characterized by their wavelength, which is the distance between two crests, and their period, the time it takes for a particle to complete one oscillation. Energy transfer occurs from one particle to another, causing them to oscillate in a sequential manner, but this does not affect the overall time period of the wave. Each particle oscillates in a slightly different phase, yet they all complete their cycles within the same time frame, allowing for the formation of a complete wave. The discussion emphasizes the importance of understanding the relationship between wavelength, frequency, and time period in wave mechanics. Clarifying these concepts can enhance comprehension of how waves propagate through a medium.

So it just happens that the time taken for one wave to be completed and one particle to
Complete its oscillation is the same ?

"Just happens"? The one follows from the other. Try to imagine what would happen if they weren't and what you would observe at one point in space.

I understand the movement had to be consecutive for it to be a wave but why are they nth exactly one period? Cant one be more or less?

How could a particle be moving at a different frequency from the frequency of the wave? Where would it be getting the force to make it move at that (different) rate?

I think you need to stop and take a breath on this one. You seem to hanging onto something that just has to be nonsense. Why?

Simplest I can think is this :

1. Wavelength is the distance between 2 crests or troughs. 1 crest/trough is a wavefront. The distance between 2 wavefronts is a wavelength. Wavelength is one complete wave motion indeed. Because between 2 crests you have one wavelength.

You can only denote wavelength when it is one particular instant of the wave. Time is not considered here; like in a picture.

2. If you're seeing 2 graphs of displacement against distance and displacement against time, you'll notice that the representation of wavelength and time are both the same. Time period is the time taken for a wave ( considering all the particles synced ) to do 1 complete wave motion. So you now understand the relationship between wavelength and time period.

Ok so since the frequency f the particle is dependent in the frequency of the source so for example in a ripple tank when the dipper goes down particles start To move and then a wave is formed then when the dipper goes down another time the first particle starts off another round of oscillations and another wave is formed. Is this what you are trying to say?

Ps:I realized I forgot about the source

@jadaav thanks! Very clear explanation on your part. I understand what you are trying to say.

Yeah I know. I had some problems with this chapter also. But finally got to understand it.
I'm sure you're learning the same that I was some months back ;)

Also the frequency of a wave cannot change when it is in motion ( atleast up to I know; I'm still learning myself lol ). So what was I saying ?

Yeah, the frequency of a wave depends on the frequency of vibration of the source. So once the wave is produced, the frequency cannot change.

V=f\lambda

You'll notice that in the ripple tank, when the wave travels from deeper into shallower :

1. Its frequency does not change ( as mentioned above )
2. Its speed decreases.
3. Its wavelength decreases.

There are many things more. Well that's up for you to learn.
