The angle between the two mirrors in the figure is a right angle. A beam of light in the vertical plane P strikes the mirror 1 as shown. The distance travelled by the light before striking mirror 2 is:
Options:
Answer:
C
Solution:
The beam makes 30° with the normal to mirror 1, so after reflection it goes 30° from the normal.
Mirror 2 is 1 m away along mirror 1, so the horizontal run is 1 m.
