Two waves are given by $y_1 = a \sin(\omega t - kx)$ and $y_2 = a \cos(\omega t - kx)$. The phase difference between the two waves is

Write the equation for wave speed in terms of wavelength and frequency.

$A$ simple harmonic progressive wave is represented as $Y = A \sin 2 \pi (n t - \frac{x}{\lambda}) \text{ cm}$. If the maximum particle velocity is four times the wave velocity,then the wavelength of the wave is

Define wavelength and state its $SI$ unit.

$A$ progressive wave travelling along the positive $x-$ direction is represented by $y(x, t) = A \sin(kx - \omega t + \phi)$. Its snapshot at $t = 0$ is given in the figure. For this wave,the phase $\phi$ is

The speed of a wave in a certain medium is $960\, m/s$. If $3600$ waves pass over a certain point of the medium in $1\, minute$,the wavelength is .... $metres$.
