A wave y= 3mm `sin (2pix-200 pit)` is

Propagating in the left string. It strikes the boundary at x=0 and is reflected partially and tranmitted partially. Choose the corrects statements (s)

Options

A. The tension in strings is 10 N
B. the amplitude of transmitted wave is 2mm
C. the wave undergoes a phase change of `pi` on reflection
D. the wavelength of transmitted wave is `1/2` m

Answer

A, B, C, D

Explanation

Since wave is moving in lighter string towards heavier, so joint will be treated as fixed end for reflection of wave.
