Question

The reflecting surfaces of two mirrors form a vertex with an angle of 100 .

Part A

If a ray of light strikes mirror 1 with an angle of incidence of 52 , find the angle of reflection of the ray when it leaves mirror 2.

Express your answer using two significant figures.

The reflecting surfaces of two mirrors form a vertex with an angle of 100 .

Part A

If a ray of light strikes mirror 1 with an angle of incidence of 52 , find the angle of reflection of the ray when it leaves mirror 2.

Express your answer using two significant figures.

let say and if imagine ABC is a triangle

B = vertex that the angle iis reflecting surfaces meets

so CBA = 90 - 52 = 48o

and the angle is BAC = 180 - ( 48 + 100 )

= 32o

so now the angle of reflection of the ray when it leaves mirror 2 is

= 90 - 32

= 58o

the angle of reflection of the ray when it leaves mirror 2 is = 58o
