Refracted angle is always greater than the incidence angle.

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.

State whether the following statement is true or false.
If the angle of incidence is greater than the critical angle, light is not refracted at all, when it falls on the surface from a denser medium to a rarer medium.

Q. State whether true or false:

Q.

Question 74

State whether the statement is True or False.

Sum of any two angles of a triangle is always greater than the third angle.

Q. 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.
