Discuss the law of reflection with diagrams? Define the index of refraction with example?

Expert Solution
Step 1:Explanation of Law of reflection

According to the law of reflection , when light hits on a smooth surface ,the incident angle will be equal to the reflected angle and the incident ray , normal ray and reflected ray all lie in the same plane .Thus the law of reflection consists of two conditions:

  • When light ray falls on a smooth surface ,the angle made by incident ray with respect to the normal line should be equal to the angle made by reflected ray with respect to the normal line.
  • When light ray falls on a smooth surface ,the incident ray, reflected ray and normal should all lie in the same plane.

The diagram describing the law of reflection is given below:
