Question

Boojho stands at A just on the side of a plane mirror as shown in Fig. 16.20. Can he see himself in the mirror? Also can he see the image of objects situated at P, Q and R?

Answer 1

Mirror Reflection:

The image given in the question is attached below.

Explanation:

• From image we can see that Boojho in point A is not in front of the mirror. So, he/she cannot see himself in the mirror.
• Boojho can definitely see the objects at the points P and Q through the image. This is because light from the object is reflected by the mirror and are seen by Boojha.
• From image, Boojha may or may have not seen the object kept in the point R. This is because the point R is far away from the mirror. The light from the object may or may not fall on mirror. If it is reflected by the mirror, then the object at the point R can be seen by Boojha.

Answer 2

Plane mirror

Explanation:

Bojhoo cannot see his image in the mirror when he is standing at A, as he is not standing in front of the mirror because the length of the mirror is too short on his side.  

At P and Q, Boojho can see his images in the plane mirror as the light rays from P and Q get reflected from the mirror.

At R, Boojho is not in front of the mirror. So he won't be able to see the image. Please refer to the attached picture for the ray diagram.
