A transverse wave on a rope is given by the following equation.
y(x, t) = ( 0.710 cm ) cos pi [(0.400 cm^-1)x + (500 s^-1)t]
From this, find the amplitude, period, frequency, wavelength and the speed of propogation.
Well, I know that v=f*lambda. I also know the general equation for sinusodal models in the -x direction:
(I choose to use this particular equation because it ties in with the one given to me)
The Attempt at a Solution
This problem is driving me nuts. I should be able to just take out the units that it aligns with and get that for the answer, right? I took out the 0.71, so I found the amplitude. I found the frequency by dividing 500 by 2. I found the period by dividing 1/250. But I can't for the life of me find the wavelength or the speed of propogation, can anyone please help? Thanks very much!
