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.[1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed.

Answer 2

Explanation:

• Refraction of light takes place when light travels from one medium to another.
• It takes place at the boundary between the two mediums.
• Also, we know that speed of light is different in different mediums.
• So, it occurs due to the change in speed of light on going from one medium to another.
• Refractive index of medium 2 with respect to medium 1 is equal to the ratio of speed of light in medium 1 to the speed of light in medium 2.
