Question

A prism kept in different medium of different refractive index will have

• A. different angle of deviation
• B. same angle of deviation
• C. angle of deviation is independent to refractive index
• D. none of the above

Answer 1

The correct option is A different angle of deviation

Since refractive index of a medium can be relative i.e refractive index of 1 w.r.t 2 is ${}_2{\mu }_1=\frac{{\mu }_1}{{\mu }_2}$

Hence angle of deviation of a ray changes for change in surrounding of a prism.
