Question

The angle between an incident ray and the reflecting surface is 55°. What will be the total angle between the incident and reflected ray?Immersive Reader (1 Point) 60° 70° 55° 90°

Answer 1

Answer:

70°

Explanation:

The angle between the reflecting surface and the incident ray is 55°.

So, the angle of incident rays with normal =(90-55)°=35°

Now we know that :-

Angle of incidence = Angle of reflection = 35°.

The total angle between incident and reflected ray:

= (35+35)° = 70°
