A sinusoidal wave of amplitude A and wavelength \( \lambda \) is incident from heavier string on a joint between two strings of which one is heavy and another is light. Choose correct option.
\( \mathrm{P} \)
(A) the amplitude of transmitted wave is more than that of the incident wave
(B) the wavelength of the transmitted wave is more than that of the incident wave.
\( \mathrm{W} \)
(C) the amplitude of the reflected wave is less than the amplitude of incident wave.
(D) the wavelength of the reflected wave is same as that of the incident wave.
