Detailed explanation-1: -refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow.
Detailed explanation-2: -Absorption is when a wave comes into contact with a medium and causes the medium’s molecules to vibrate and move. This vibration absorbs or takes some of the energy away from the wave and less of the energy is reflected. One example of absorption is black pavement which absorbs energy from light.
Detailed explanation-3: -When light suffers reflection at the interference between air and glass, the charge of phase of reflected wave is 180o.
Detailed explanation-4: -Sound waves can travel through gases and liquids, but not solids. Most of the sounds we hear reach our ears through the air, but sounds can also travel through liquids and solids.
