The beam of light in the vertical plane P strikes mirror 1 at 01-49.6 as shown. Light beam Mirror 1.25 m Mirror (a) Determine the distance the reflected light beam travels before striking mirror 2. (b) In what direction does the light beam travel after being reflected from mirror 22 °above the horizontal Need Help?ah 200 PM de O Type here to searchExplanation / Answer
(a)
If x is the distance:
x = 1.25 / sin(49.6)
= 1.64 m.
(b)
The beam reflects from mirror 1 at 49.6 deg. to the vertical, strikes mirror 2 at 40.6 deg. from below the horizontal, and is reflected at 40.6 deg. above the horizontal.
