When a sound wave gets reflected from denser medium phase changes by

A ray of light is incident from air on a glass plate. It is partly reflected and partly refracted. The phase difference between the reflected and refracted wave is :

When sound waves are reflected from a denser medium

A wave travelling in air falls on a glass plate . It is partly reflected and partly refracted. What is the phase difference between the reflected and refracted waves ?

When a longitudinal wave is reflected from a rarer medium, the phase change produced is
