Statement 1: Angle of incidence is greater than the angle of refraction.
Statement 2: Angle of incidence is lesser than the angle of refraction.
Statement 3: Angle of emergence is equal to the angle of incidence.
Which of the following is/are correct with respect to refraction in a glass slab?

Q. In the experiment to trace the path of a ray of light through a parallel sided glass slab, a student measured the angles of refraction for three different angles of incidence. He will find that:
(1) angle of refraction is always equal to the angle of incidence
(2) angle of refraction is always smaller than the angle of incidence
(3) angle of refraction is always greater than the angle of incidence
(4) angle of refraction can be smaller or greater than the angle of incidence depending on the refractive index of glass slab

Q. Mark the correct statement/statements:
a) Angle of incidence is equal to angle of refraction
b) Angle of refraction is smaller than angle of incidence when light ray travels from rarer medium to denser medium.
c) Angle of refraction is greater than angle of incidence when light ray travels from denser medium to rarer medium.

Q. In an experiment to study the refraction of light through a rectangular glass slab, a student measured the angle of incidence, angle of refraction and the angle of emergence. The student lost the reading of angle of incidence but noted the readings of angle of refraction to be 35° and angle of emergence to be 65°. The angle of incidence is likely to be:
(1) 45°
(2) 55°
(3) 35°
(4) 65°

Q.

A ray of light passes from glass into air, angle of refraction; (a) equal to the angle of incidence (b) greater than the angle of incidence (c) smaller than the angle of incidence (d) ${45}^{\circ }$

Q. A teacher asked four students to record the observations of the experiment on tracing the path of a ray of light through a rectangular glass slab. The students recorded their observations under the following headings:
(1) Angle of incidence, Angle of refraction, Angle of reflection
(2) Angle of incidence, Angle of deviation, Angle of emergence
(3) Angle of incidence, Angle of reflection, Angle of emergence
(4) Angle of incidence, Angle of refraction, Angle of emergence
The correct observations were recorded by the student:
(1) A
(2) B
(3) C
(4) D
