Question
Two strings, A and B, of lengths 4L and L respectively and same mass M each, are tied together to form a knot 'O' and stretched under the same tension. A transverse wave pulse is sent along the composite string from the side A, as shown to the right. Which of the following diagrams correctly shows the reflected and transmitted wave pulses near the knot 'O'?
Options
A.
B.
C.
D.
Solution
Sol. μA = M/4L, μB = M/L
As μB>μA, Sowave reflected from heavier string will have phase change of π, and hence inverted. Whereas transmitted wave will be not be inverted.
