Question

the angle between reflecting surface and its incident ray is 40, then find the angle of incident and angle of reflection
​

Answer 1

Answer:

Angle between mirror and incident ray = 40°

angle between mirror and the normal ray = 90°

therefore, the angle of incidence = 90°-40° = 50°

so the angle of reflection=angle of incidence= 50°

hope it helped :)

Answer 2

Answer:

angle of incidence=angle of reflection= 50°

Explanation:

angle betn reflecting surface and its incident ray is 40 then angle of incidence will be 50 (90-40)as when we add them we get 90 .

According to law of reflection,

angle of incidence=angle of reflection

angle of incidence=angle of reflection= 50°
