Refraction of light through a glass slab

Four students A, B, C and D selected the following items from the materials available in the science laboratory to perform an experiment to study the refraction of light through a glass slab : (A) convex lens, glass slab, pins, drawing board, white paper, scale (B) glass slab, pins, drawing board, scale, white paper, protractor (C) glass slab, glass prism, candle, screen, pins, scale, drawing board, protractor (D) concave mirror, pins, glass slab, protractor, white paper, drawing board Correct choice of the items required is made by the student :

During refraction of light through the glass slab, incident ray and emergent ray are perpendicular to each other. True/false

'During refraction of light through the glass slab, incident ray and emergent ray are parallel to each other.' Explain.

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 :
