Refraction of light passing through a glass slab.

Obtian the equation for lateral displacement of light passing through a glass slab.

In an experiment to trace the path of a ray of light passing through a rectangular glass slab, four students tabulated their observations as given below. Which student is correct.

When light passes through glass slab, the incident ray and emergent ray are ……………………. .

If the angle incidence and angle of emergence of a light ray falling on a glass slab are i and e respectively, then prove that, i=e.

Critical angle of light passing from glass to air is minimum for
