1.	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 of 300 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[IIT-JEE (Screening) 2002]

Answer»

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 of 30⁰ 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
