A glass prism is immersed in a hypothetical liquid. The curves showing the refractive index n as a function of wavelength \lambda for glass and liquid are as shown in the figure. When a ray of white light is incident on the prism parallel to the base:

Yellow ray travels without deviation

Blue ray is deviated towards the vertex

Red ray is deviated towards the base

A glass prism is immersed in a hypothetical liquid. The curves showing the refractive index n as a function of wavelength λ for glass and liquid are as shown in the figure. When a ray of white light is incident on the prism parallel to the base:

Yellow ray travels without deviation
Blue ray is deviated towards the vertex
Red ray is deviated towards the base
There is no dispersion
