Question

what happens when:
The light falls on the mirror at 900

Answer 1

Answer:

When light falls on a mirror, it get reflected. When light falls on a mirror, reflection occurs and the light ray is said to be reflected.

Explanation:

Answer 2

Answer:

According to law of reflection, angle of incidence is equal to angle of reflection.

∠mxy=∠mxd=30o

Also ∠mxy=∠xyo

⟹ ∠xyo=30o

∠cyx=90o−∠xyo

We get  ∠cyx=90o−30o=60o

Again from law of reflection, ∠cyx=∠cyp

⟹ ∠cyp=∠N=60o
