Refraction in a Rectangular Slab
In a rectangular slab, refraction takes place at two interfaces.
Explanation:
- A rectangular slab can be considered as a prism with a rectangular cross-section.
- When a ray of light enters the slab from air (or any other medium), it undergoes refraction at the first interface between air and the slab.
- The angle of incidence and the angle of refraction are related by Snell's law: n1 sinθ1 = n2 sinθ2, where n1 and n2 are the refractive indices of air and the slab, respectively, and θ1 and θ2 are the angles of incidence and refraction, respectively.
- The refracted ray travels through the slab and undergoes refraction again when it exits the slab and enters air (or any other medium).
- The angle of incidence and the angle of refraction at the second interface are related by Snell's law in a similar manner.
- Therefore, refraction takes place at two interfaces in a rectangular slab.
Conclusion:
Refraction in a rectangular slab takes place at two interfaces, one when the ray enters the slab and another when it exits the slab.

The refraction takes place at both air-glass interface and glass-air interface of a rectangular glass slab. When the light ray incident on air-glass interface (DC) obliquely, it bends towards the normal
