Two plane mirrors intersect at right angles. a laser beam strikes the first of them at a point 11.5 cm from their point of inter

section, as shown in fig. e33.1 for what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0 cm long) after reflecting from the first mirror?
