Question

with the help of ray diagram show that angle of incidence is equal to angle of reflection when a ray is incident on concave mirror

Answer 1

With the help of ray diagram show that angle of incidence is equal to the angle of reflection when a ray is incident on the concave mirror. In the ray diagram shown below CB is the normal and $\angle$i = $\angle$r, AB is the incident ray and BD is the reflected ray.

Answer 2

"From the above ray diagram shows a incident ray on the concave mirror. And it shows that the reflection angle is equal to the incident angle.

AB indicates –Incident ray and BD indicates – Reflected ray.

CB indicates – Normal ray.

If ray is incident on the concave mirror it produce an angle “i” and it’s reflected to produce an angle “r”.

From the diagram angle of “I” is equal to the angle of “r”."
