Differentiate between a glass slab and a glass prism.
Advertisements
Solution
Glass slab: It is rectangular in shape and made up of glass. In glass slab, the direction of the incident ray and the emergent ray of light are parallel to each other.
Glass Prism: It has two triangular sides, two inclined rectangular sides, and one rectangular base. In glass prism, the direction of the incident ray and the emergent ray of light is not parallel to each other.
