A wave pulse, travelling on a two-piece string, gets partially reflected and partially transmitted at the junction. The reflected wave is inverted in shape as compared to the incident one. If the incident wave has wavelength `lambda` and the transmitted wave `lambda` then

Options

A. `lambda^(l) gt lambda`
B. `lambda^(l)= lambda`
C. `lambda^(l) lt lambda`
D. Nothing can be said about the relation of `lambda and lambda^(l)`

Answer

C
