oksano4ka [1.4K]

Answer:

angle of incidence for the second mirror is 55.4 degree  

Explanation:

Given data;

Angle between two mirror is 90 degree

Incident angle on first mirror is 34.6 degree

For first mirror

Angle of incidence  is equal to  angle of reflection

34.6 degree = angle of reflection

r_1 = 42.5 degree

Now , for the triangle ABC         [from figure]

90 - r_1 + 90 + 90 - i_1 = 180

34.6 + i_1 = 90

i_1 = 55.4 degree

The angle of incidence for

angle of incidence for the second mirror is 55.4 degree
