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. The greatest distance over which he can see the image of the light source in the mirror is:

Two plane mirrors A and B are aligned parallel to each other, as shown in fig. A light ray is incident at an angle of 30^o at a point just inside one end of A. The plane of incidence coincides with the plane of the figure. The maximum number of times the ray undergoes reflection (including the first one) before it emerges out is:
