What causes light to bend when it moves from one transparent medium to another?


a change in amplitude


a change in color


a change in frequency


a change in speed

Verified Answer :

change in speed is the answer

Answer: The correct answer is - change in speed.

When light travels from one transparent medium to another transparent medium, it bends and this phenomenon is known as refraction.

It is caused due to difference in the speed of light in different medium as speed of light is slow in a denser medium (like water) whereas speed is faster in a lighter medium (like air).
