The equation given below represents a stationary wave set-up in a medium y=12sin(4pix)sin(4pit) where y and x are in cm and t is in second. Calculate the amplitude, wavelength and velocity of the component waves.

Two wires of radii r and 2 r are welded together end to end . The combination is used as a sonometer wire and is kept under a tension T . The welded point lies midway between the bridges. The ratio of the number of loops formed in the wires , such that the joint is a node when the stationary waves are set up in the wire is

One end of a taut string of length 3m along the x-axis is fixed at x = 0 . The speed of the waves in the string is 100ms^(-1) . The other end of the string is vibrating in the y-direction so that stationary waves are set up in the string. The possible wavelength (s) of these sationary waves is (are)

The stationary waves set up on a string have the equation : y = ( 2 mm) sin [ (6.28 m^(-1)) x] cos omega t The stationary wave is created by two identical waves , of amplitude A each , moving in opposite directions along the string . Then :
