In a transverse wave, the distance between two successive troughs is lamda//2

The phase difference between two points separated by 1m in a wave of frequency 120 Hz is 90^(@) . The wave velocity is

The phase difference between two points separated by 0.8 m in a wave of frequency 120 Hz is 0.5pi . The wave velocity is

In a transverse wave, the distance between two successive troughs is 1/2 of the wavelength.

The path difference between two interfering waves at a point on screen is 70.5 tomes the wave length. The point is

The distance between two consecutive crests in a wave train produced in string is 5 m. If two complete waves pass through any point per second, the velocity of wave is :-

y_1 = 8 sin (omegat - kx) and y_2 = 6 sin (omegat + kx) are two waves travelling in a string of area of cross-section s and density rho. These two waves are superimposed to produce a standing wave. (a) Find the energy of the standing wave between two consecutive nodes. (b) Find the total amount of energy crossing through a node per second.

A stretched string is in resonance with a tuning fork of frequency 250 Hz. If the distance between two consecutive antinodes on the string is 5, then the velocity of the progressive wave in the string is
