Question

What is the angle of incidence when the direction of incident ray A1A2O coincides

with that of the normal NO in Fig. 6.2.

(ii) What should be the angle of reflection when the incident ray falls normally on the

surface of the mirror strip?

(iii) If you join A1 with A′

1 by a straight line, then in what ratio the line M1M2 divides

the line A′

1A1?

(iv) If the incident ray makes an angle of 30° with the plane of mirror, i.e. with M1M2,

then what will be the angle of reflection?

(v) If a pin is fixed at a distance of 4 cm in front of a plane mirror where and at what

distance will the image be formed?

(vi) You are advised to take a thin mirror strip to verify the laws of reflection. why?​
