• ## 2. Causes Of Refraction of Light Physics Class 10

Cause of Refraction : The speed of the light in different transparent substances is different. For example speed of light in air is 3×10⁸ m/s and that of in glass is 2×10⁸ m/s. It is clear that the two speeds of the light are different. When light enters from air to glass the speed of…

• ## 1 Refraction of Light Definition and Introduction Physics Class 10

Refract means bending. The bending of ray of light when it pass from one medium to another medium is known by a term called refraction. Refraction of Light happens due to different speed of light in different medium. Speed of light in air is 3×10⁸m/s and that of in glass is 2×10⁸m/s. Refraction of Light:…
