Question

If the angle of incidence formed on a plane mirror is 63°, what will be the measure of the angle of reflection?​

Answer 1

Required Answer:

${\underline {\boxed {\Large {\bf \gray { \angle r = {63}^{\circ} } }}}}$

Explanation:

• Second law of reflection states that "angle of incidence is always equal to angles of reflection". i.e, $\rm \blue { \angle i = \angle r }$ ( in both

So, here we are given that :

⇒ Angle of incidence is 63°

• By using the 2nd law of reflection, it is crystal clear that "the angle of reflection will be 63°".

More Information:

• Reflection is the bouncing back of the light when it strikes on the surface.

Laws of reflection :

• First law of reflection states that the reflected ray, incident ray and normal lie in the same plane.

[Normal is the perpendicular line to the point of the incidence or where the light strikes the surface.]

• Second law of reflection states that the angle of incidence is always equal to angle of reflection.

Answer 2

Answer:

63degrees itself is the answer.

Explanation:

We know that there are three laws in reflection

So , we have to use second law of reflection which is angle of incidence = angle of reflection.

 ∵ Therefore 63degrees = 63 degrees itself.

Which means 63=63.
