Reflection Of Light By Spherical Mirrors

From Melde's law
constant
hence,


so

Velocity of electromagnatic wave in space is

Step 1: Understand the law of reflection The law of reflection states that: Given: Step 2: Find the angle between the incident and reflected ray The incident ray and the reflected ray are on opposite sides of the normal, and each makes a angle with the normal. So the angle between them is: Answer: The correct answer is option (2) .
