it is NOT correct that a stationary wave has no velocity. a stationary wave is caused by 2 waves traveling with the same velocity v in opposite directions. thus, for each separate wave:hotel said:Hi
what is the relation between wavelength (L) and frequency (f) ?
I know that
L = c/f
but if we have a stationary wave with no velocity (c), can we express wavelength with:
L = 1/f ?
so that we can better understand your comments, please post your actual problem and your work so far in solving it.hotel said:why frequency must be inverse function of time ? It can be inverse function of space as well I think, like f = 1/meter (number of cycles per meter)?!
If stationary waves have opposite velocities then practically they should cancel each other and the resultant velocity will be zero!
In my case, I have an steady state problem, where waves are function of space and not function of time. I don't think it make sense to use c when waves are not time dependent.
If L=1/f is not correct, how do we find the wavelength ?
( L=1/f seems to be the right answer, while I thought more about it since I posted the message)
