Answer 1

Answer:

knight and subscribe 6

Explanation:

out 6 hey guys I'm a big

Answer 2

Answer:

Angle of Incidence=Angle of Reflection=48 °

Explanation:

Given: if the angle of incidence of a Ray of light is 42 degree what is each of the following the angle of reflection the angle of incident ray makes with the mirror the angle between incident ray and reflected ray​

To find: What is the angle of incident ray makes with the mirror the angle between incident ray and reflected ray​

Solution: Angle of Incidence=Angle of Reflection ( Laws of Reflection )

Angle of Reflection + Angle between Reflected ray and Surface of Mirror = 9 0 °

Let r be the angle of reflection , then :

r +  4 2  ° = 9 0  °

r = 9 0 – 4 2 = 4 8  °

Angle of Incidence = Angle of Reflection = 4 8  °
