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.

Does the wave function y=A_(0) cos^(-2)(2pi f_(0)t(2pi x)/(lambda_(0))) represent a wve ?if yes. Then determine it's amplitude, frequency and wave-length .

A plane progressive wave is represented by the equation y= 0.25 cos (2 pi t - 2 pi x) The equation of a wave is with double the amplitude and half frequency but travelling in the opposite direction will be :-

If f_(0) and f_(f) represent the carrier wave frequencies for amplitude and frequency modulations respectively, then

If f_(0) and f_(f) represent the carrier wave frequencies for amplitude and frequency modulations respectively, then

Y= 2A cos^(2) (kx - omega t) represents a wave with amplitude A´ and frequency f. The value of A´ and f are:
