Question

If the angle of incidence is ${50}^o$, then calculate the angle between the incident ray and the reflected ray:

• A. ${50}^o$
• B. ${260}^o$
• C. ${100}^o$
• D. ${80}^o$

Answer 1

The correct option is C ${100}^o$

According to the law of reflection, the angle of incidence equals the angle of reflection.
In this case, the angle of incidence is 50 degrees. So the angle of reflection will also be 50 degrees.
So the angle between both the angle of incidence and angle of reflection is 50 + 50 = 100 degrees.
