A point source of light B is placed at a distance L in front of the center of a mirror of width d hung vertically on a wall. A man walks in front of the mirror along a line parallel to the mirror at a distance 2L from it, as shown in Fig . Find the greated distance over which he can see the image of the light source form the mirror.

A point source of light S, placed at a distance L in front of the centre of a mirror of width d, hangs vertically on a wall. A man walks in front of the mirror along a line parallel to th mirror at a distane 2L form it as shown.The greatest distance over which he can see the image of the light source in the mirror is (a) d//2 (b) d (c) 2d (d) 3 d.

A point source of light S, placed at a distance 60 cm infront of the centre of a plane mirror of width 50 cm, hangs vertically on a wall. A man walks infront of the mirror along a line parallel to the mirror at a distance 1.2 m from it (see in the figure). The distance between the extreme points where he can see the image of the light source in the mirror is .......... cm.

A point source of light ,S is placed at a distance L in front of the centre of plane mirror of width d which is a hanging vertically on wall ,A man walks in front of the mirror , at a distance 2L as shown below . The distance over which the man can see the image of the light source in the mirror is :

A point source of light S is placed at a distance 10 cm in front of the centre of a mirror of width 20 cm suspended vertically on a wall. An insect walks with a speed 10cm//s in front of the mirror along a line parallel to the mirror at a distance 20 cm from it as shown in figure. find the maximum time during which the insect can see the image of the source S in the mirror.
