| 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. A ray of white light is incident on the prism parallel to the base. Choose the incorrect statement - |
 |
A) yellow ray travels without deviation
B) blue ray is deviated towards the vertex
C) red ray is deviated towards the base
D) there is no dispersion
Correct Answer: D
Solution :
| [d] n for liquid \[=n\] for glass for yellow light But n for liquid \[<n\] for glass (red light) |
| \[\therefore \] deviated towards base |
| Similarly, n for liquid \[>n\] for glass (blue light) |
| \[\therefore \] deviated towards vertex. |
