Question

13.What is Refraction of light? Explain with a neat ray diagram, when a light ray travelling from rarer to denser medium and Denser medium to Rarer medium.​

Answer 1

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.

Explanation:

Answer 2

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction
