Question

if the angle of incidence is 40 Degrees then calculator the angle between the incident ray and the reflected ray​

Answer 1

Answer:

Angle between Ray of Incidence and Ray of Reflection is 80°

Explanation:

To find the angle between Incident Ray and Reflected ray.

Rules of reflection-

1. Angle of incidence and angle of reflection is always equal. Which is the angle between Ray if Incidence and Normal(the line of point between Ray of Incidence and Ray of Reflection) and Ray of Reflection and Normal.
2. Ray of Incident, Normal and Ray of Reflection lies in same plane(which also mean that Normal, the line, will always divide angles of Incidence and Reflection in 2 equal parts).

Now, the Angle of Incidence is 40° so angle of reflection will also be 40° as Rule 1 claims so(Angle of incidence and angle of reflection is always equal).

So, The sum of angles is 80°(40°+40°) which is the Angle between Ray of Incidence and Ray of Reflection.
