Detailed Solution

Speed of sound is maximum in water, hence water is rarer medium for sound waves w.r.t. air.

Longitudinal pressure waves suffer no change in phase from rigid end i.e. compression pulse reflects as compression pulse. On the other hand if longitudinal pressure wave reflects from free end, it suffer a phase change of π i.e. compression reflects as rarefaction and vice-versa.

No phase change happens during transmission.
