Question
The angle between the incident ray and the reflecting surface is 35 degrees. The angle of incidence is ___ degrees.
Hint:
If the angle between the incident ray and the reflecting surface is 35 degrees, the angle of incidence is 55 degrees.
The correct answer is: 55
- The angle of the normal from the reflecting surface is 90 degrees.
- To get the angle of incidence, the angle between the incident ray and the reflecting surface can be subtracted from the normal ray.
- So, 90- 35= 55. The angle of incidence is 55 degrees.
