A transverse wave is represented by y = A sin(ωt - kx). The value of wavelength (λ) for which the wave velocity is equal to the maximum particle velocity will be:

For a travelling harmonic wave y(x, t) = 2.0 cos 2π(10 t - 0.0080 x + 0.35), where x and y are in cm and t in s. The phase difference between oscillatory motion of two points separated by a distance of 0.5 m is:

The equation of a plane progressive wave is given by y = 5 cos π (200t - x150), where x and y are in cm and t is in seconds. Find the wave velocity in m/s.
