Question

An irregular crystal structure reflects all the light that falls on it’s as shown in the diagram.

Which of the following statements is/are true?

• A. Laws of reflection doesn’t hold good.
• B. Law of reflection (∠i = ∠r) only holds good.
• C. Law of reflection, “incident, reflected and normal all lie in the same plane” only hold good.
• D. Both law's of reflection hold good.

Answer 1

Answer: (B), (C)

The correct options are
B

Law of reflection (∠i = ∠r) only holds good.

C

Law of reflection, “incident, reflected and normal all lie in the same plane” only hold good.

Laws of reflection hold true for all kind of reflecting surfaces. Since the above surface is irregular, the normal will be in different directions at different points but the laws of reflection will be applicable at each of these minute surfaces where light is incident.
