Solution

The correct option is A Zero rad
For a transverse wave, a phase change of $π$ occurs when it is reflected from a denser medium.
When reflected from a free end, however, there is no change of phase.
Hence the correct answer is option A.

A transverse wave on a string is described by the equation

Q. A transverse sinusoidal wave is generated at one end of a long horizontal string by a bar that moves the end up and down through a distance by 2.0 cm. The motion of bar is continuous and is repeated regularly 125 times per second. If the distance between adjacent wave crests is observed to the 15.6 cm and the wave is moving along positive x-direction, and at t = 0 the element of the string at x = 0 is at mean position y = 0 and is moving downward, the equation of the wave is best described by
