The region of total reflection begins …

WebRefraction is the change of direction of a wave when it travels from a medium in which it has one velocity to a medium in which it has a different velocity. Refraction of sound occurs in the ocean because the temperature or the water changes with depth, which causes the velocity of sound also to change with depth.
