Question

Q.27 The angle between the incident ray and reflected ray is 166º. What is the
value of angle of incidence. State the two laws of reflection..​

Answer 1

Answer:

Angle of incidence = 166°/2 = 83°

•The incident ray the refracted Ray and the normal lie in the same plane at the point of incidence

•The angle of incidence is always equal to the angle of refraction

Answer 2

law of reflection :

• the angle of incidence is equal to angle of reflection.
• the incident ray, the reflected ray and the normal at the point of incidence, lie in same plane.
• Angle of incidence =7
