Answer:
∠ABN1 and ∠BCN2 are the angles of incidence.
Explanation:
In the given question, ray AB is incident on plane mirror M1.
The angle of incidence will be ∠ABN1 = 45°.
Since we know that the angle of incidence is equal to the angle of reflection, hence, ∠CBN1 will also be equal to 45°.
Now we can see that triangle ΔCOB is an isosceles right-angled triangle.
i.e. ∠OCB= ∠OBC= 45° and ∠COB= 90°.
Now, on constructing normal at C, the angle of incidence at C (for mirror M2) will be 45°.
This implies that the angle of reflection ∠DCN2 will also be equal to 45°.
In this question, it is necessary for the student to place arrowheads upon the rays since it indicates the direction in which the ray travels.
