If a small angled prism, made of glass is immersed in a liquid of refractive index '1' and a ray of light is made to incident on it, then :

Aits deviation will be zero
Bit will suffer total reflection
Cthe emergent ray is bent towards the edge of the prism
Dthe emergent ray is bent towards the base of prism
Correct Answer

Solution

liquid has refractive index 1 and of glass we know it is 1.5 so, when ray is incident on the prism it is bent towards the normal in the prism as shown in figure
so, by figure it is clear that emergent ray is bent towards the base of prism.
