Question

If the light had the same speed in air and in the glass, the light will not get refracted while entering glass from the air.

• A. Yes
• B. No

Answer 1

The correct option is A

Yes

The main cause of refraction is the change in speed of light while going from one medium to another.

So if the speed of light remains constant, the light will not bend or get refracted while entering glass from the air.
