State whether the following statement is true or false:Refraction occurs because light slows down in denser materials.
The given statement is true.
Explanation
Refraction is the process of bending of light when light travels from one medium to another medium. The angle of refraction or the amount of bending of light depends on the densities or refractive index
1. When light passes through a low refractive index, like air (faster medium or optically rarer medium) to a high refractive index, like glass(slower medium or optically denser medium), its speed decreases and bends towards the normal.
2. When light passes through a high refractive index, like glass (slower medium or optically denser medium) to a low refractive index, like air (faster medium or optically rarer medium) its speed increases and bends away from the normal.
