Question

A converging beam of light rays incident on a glass-air interface as shown. Find where these rays will meet after refraction.

Answer 1

The rays will meet at a distance of 20 cm below the interface.

Answer 2

The problem describes a converging beam of light rays incident on a glass-air interface. The diagram provided shows the incident rays and the refracted rays. The refracted rays are depicted as dashed lines and are shown to converge at a point. The distance of this point of convergence from the interface is explicitly marked as 20 cm. The question asks to find where these rays will meet after refraction. Based on the diagram, the refracted rays meet at a point 20 cm below the interface, inside the glass.
