state about refraction of light
Answers
Answer:
Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.

Answer:
Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.
Defining Refraction
“Refraction is the change in the direction of a wave passing from one medium to another.”
Refraction of light is one of the most commonly observed phenomena, but other waves like sound waves and water waves also experience refraction. Refraction makes it possible for us to have optical instruments such as magnifying glasses, lenses and prisms. It is also because of the refraction of light that we are able to focus light on to our retina.
