Q1. When light passes from air into glass, it bends towards the normal. This phenomenon is called:
Answer: Refraction
Explanation: Refraction occurs when light passes from one medium to another with a different optical density, causing a change in speed and therefore a change in direction. When light enters glass from air, it slows down and bends toward the normal because glass has a higher refractive index than air.
