Two perpendicular plane mirrors are placed as shown in figure. The light rays AB and CD will be parallel for D K A B

Two mirrors are inclined at angle theta as shown in figure. Light rays are incident parallel to one of mirrors. Light will start retracing its path after the reflection if

Two plane mirrors A and B are aligned parallel to each other, as shown in the figure. A light ray is incident at an angle 30degree 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 reflections (including the first one) before it emerges out is

Two plane mirrors P and Q are aligned parallel to each other, as shown in the figure. A light ray is incident at an angle of q 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 reflections (including the first one) before it emerges out is:
