Qᴜᴇꜱᴛɪᴏɴ :

What is the angle between incident ray and reflected ray, when the light ray is incident normally on the surface of mirror ?

ᴀɴꜱᴡᴇʀ :

➯ The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
