reflected rays respectively . AoB = 90° Find the
values of angle of reflection ?
​

Answer 1

Answer:

45°

Explanation:

hopi it helps

.........

Answer 2

Explanation:

ON is normal on the plane mirror at point O

ON is perpendicular on a plane mirror

Angle of incidence ∠i = ∠AON and angle of reflection ∠r = ∠BON Since, ∠i – ∠r ∠AOB = 90° ⇒ ∠AON + ∠BON = 90° ⇒∠i + ∠i – 90° ⇒ 2 ∠i =90° ⇒ ∠i = 90 / 2 = 45°

∴Angle of incidence = ∠i = 45° and Angle of reflection ∠i = 45°
