Laws of reflection state that the angle of incidence equals the angle of reflection, AND:
ABoth rays lie on the same line
BReflected ray is along the normal
CIncident and reflected rays parallel
DAll three rays lie in one plane
Answer & Solution
Correct answer: D. All three rays lie in one plane
1. First law: angle of incidence = angle of reflection (both measured from the normal).
2. Second law: incident ray, reflected ray and the normal at the point of incidence all lie in the SAME PLANE.
3. Both laws hold for any kind of reflection — plane or curved.
