Question

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

Which of the following statement is 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 holds true for all kinds of reflecting surface. Since the above surface is irregular, hence the normal at different points will be in different directions but the laws of reflection will be applicable at each of these minute surfaces where reflection is happening.
