When a ray of light from air enters a denser medium, it:

Class 10 | ICSE | Physics | Refraction of Light at Plane Surfaces | Selina

When a ray of light from air enters a denser medium, it:

a. Bends away from the normal

b. Bends towards the normal

c. Goes undeviated

d. Is reflected back

Solution:

The correct option is (b). The ray of light bends towards the normal.
The reason for this is because as the speed of light slows in a denser medium, it bends towards the normal.
