Question

Light strikes a mirror making an angle of 25 degrees to the surface . Find the angle of reflection.I need step by step explanation.

Good answer will be marked as brainliest.

Answer 1

Answer

65°

Explanation

Given, light strikes a mirror making an angle of 25° with the surface.

Draw normal to the surface of mirror.

Hence, angle between the incident ray and mirror would be 90° - 25° = 65°

Now, incident ray is making an angle of 65° with the normal. (angle of incidence)

Now, according to law of reflection,

angle of incidence = angle of reflection.

→ angle of reflection = 65°

Answer 2

Answer is 65°

Because angle of incidence is 25.° and we know that normal is perpendicular to the base .

So , base of mirror is 180° and normal =90° and angle of incidence =25° . Then , 180°- (25+90) = 180° - 115° = 65°
