Question

The diagram shows an incident ray XO and the normal ON on a plane mirror. Copy the diagram and draw the reflected ray. Find the angle of incidence and angle of reflection.​

Answer 1

The angle between incident ray and normal = 90 - 40= 50⁰

$< i = < r$

So, angle of reflection =50⁰

Angle between them = 50⁰ + 50⁰ = 100⁰
