Question 131 markMCQSection A

$In the given figure the angle of incidence and the angle of deviation respectively are:$

Light — Reflection and Refraction

Reflection of Light

Options

(A)

1 and 5

(B)

7 and 6

(C)

7 and 4

(D)

1 and 6

Official answer

The angle of incidence is the angle between the incident ray and the normal to the mirror. In this case, the angle of incidence is 7 degrees. The angle of deviation is the angle between the reflected ray and the normal to the mirror. In this case, the angle of deviation is 6 degrees.

Angle of incidence

Angle of deviation

Marking scheme

1. $Angle of incidence$
2. $Angle of deviation$

Hint

$Use the law of reflection to relate the angle of incidence and the angle of deviation.$

Quick oral answer

$The angle of incidence is the angle between the incident ray and the normal to the mirror. In this case, the angle of incidence is 7 degrees. The angle of deviation is the angle between the reflected ray and the normal to the mirror. In this case, the angle of deviation is 6 degrees.$

Common mistakes

1. $Confusing the angle of incidence with the angle of reflection$
2. $Not using the law of reflection to relate the angle of incidence and the angle of deviation$

Analysis and explanation

The angle of incidence and the angle of deviation are related by the law of reflection, which states that the angle of incidence is equal to the angle of reflection. In this case, the angle of incidence is 7 degrees, and the angle of deviation is 6 degrees.

Interesting facts

$The law of reflection is a fundamental principle in optics$

$The angle of incidence and the angle of deviation are important concepts in understanding the behavior of light$
