Does the wave function `y=A_(0) cos^(2)(2pi f_(0)t-2pix//lambda_(0))` represent a wave? If yes, the determine its amplitude frequency, and wavelength.

Text Solution

Verified by Experts

The given function can be reduced to `y=(A_(0))/(2)[1+cos{2(2pi f_(0)t-(2pix)/(lambda_(0)))}]` The amplitude, frequency and wavelength of the wave are `(A_(0))/(2).2f(0) and (lambda_(0))/(2)` respectively.
