Question

A ray of light is incident on a parallel-sided glass slab, as shown in the diagram. The angle of refraction for this ray of light is likely to be:

विकल्प

• 60°

• 33°

• 57°

• 30°

Answer 1

33°

Explanation:

By the geometric rule of alternate interior angles, the diagram explicitly shows that the angle formed next to the parallel normal line inside the glass block is exactly 33°.
