Two adjoining plane mirrors are separated by an angle of 100°. Light is incident on the first mirror at an angle of 70°. The light reflects toward the second mirror and is then reflected from it. At what angle is the light reflected from the second mirror?

Respuesta :

Answer:

The light is reflected at an angle of 30 degrees from the second mirror.

Explanation:

The situation is shown in the attached figure

As  we know that angle of incidence equals angle of reflection thus all the angles are calculated in the same manner

Angle i = 70 Thus angle r = 70 as angle of incidence and reflection are same

In triangle BFC

angle FCB equals 180 - 100 - 20 = 60 degrees

Thus The angle i' equals 90 - 60 =30 degrees

Thus the final angle of reflection is also 30 degrees.
