Two plane mirrors intersect at right angles. A laser beam strikes the first of them at a point 11.5cm from their point of inter-section, as shown in Fig. 3338 for what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0cm long) after reflecting from the firstmirror?
