According to the first law of reflection, the angle of incidence:
AHas no relation with the angle of reflection
BIs half the angle of reflection
CIs twice the angle of reflection
DEquals the angle of reflection
Answer & Solution
Correct answer: D. Equals the angle of reflection
The first law of reflection states that the angle of incidence (∠i, measured from the normal to the surface) equals the angle of reflection (∠r). Both are measured from the normal, not from the surface.
