Question
The angle between the incident ray and the reflecting surface is 53 degrees. The angle of incidence is ___ degrees.
Hint:
If the angle between the incident ray and the reflecting surface is 53 degrees, the angle of incidence is 37 degrees.
The correct answer is: 37
- The normal lies perpendicular to the reflecting surface and the angle will be 90o.
- The angle of the incident ray with respect to the surface is 53o.
- To get the angle of the incident, the angle of the incident ray with the surface can be subtracted from the normal angle.
- So, 90o- 53o= 37o. The angle of incidence will be 37o.

According to the second law of reflection, the angle of incidence is equal to the angle of reflection. Mark verified this fact by drawing the incident and the reflected rays. He also measured the angles made by the same incident and reflected rays with the reflecting surface (denoted as 1 and 2, respectively). Which of the following is true about the result that he might have got?
