Solution

The correct option is B Statements 1 and 3 are true, but statement 2 is false.
When the light ray enters the glass slab, the light ray bends towards the normal as the glass is more denser than air.
Therefore, angle of incidence is greater than angle of refraction.
As the rays emerges out of the glass slab, it bends away from the normal.
The angle of emergence is equal to angle of incidence.
