Question

An irregular crystal structure reflects all the light that falls on it’s 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 same plane” only hold good
• D. Both law's of reflection hold good

Answer 1

The correct option is D

Both law's of reflection hold good

Laws of reflection hold true for all kind of reflecting surface. Since the above surface is irregular, the normal will be in a different direction but the laws of reflection will be applicable at each of these minute surfaces where incidence is happening.
