Question

what of the following are measured from the normal drawn at incident point? i) angle of incident ii) angle of reflection,a) only(i),b) only ( i) and ( ii),c)both(i) and(ii),d)none​

Answer 1

Answer:

Explanation:

The angle formed between the normal and the incident ray at the point of incidence is called the angle of incidence. Similarly, the angle formed between the normal and the reflected ray at the point of incidence is called the angle of reflection. Angle Of Incidence Formula The angle of incidence is equal to the reflected angle through the law of reflection
