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?


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

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

  3. Both law's of reflection hold good.

  4. Laws of reflection doesn’t hold good.


Solution

The correct option is C

Both law's of reflection hold good.


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