Question

Assertion (A): The refractive index of the prism depends on the material of the prism
Reason (R): The dispersive power of the prism is independent of material of the prism
a) Both A and R are true and R is the correct explanation of the A.
b) Both A and R are true but R is not the correct explanation of the A,
c) A is true but R is false
d) A is false but R is true​

Answer 1

Answer:

Refractive index refers to the ratio of velocity of light in vacuum to the velocity of light in medium. ... We can infer that refractive index depends on the refracting angle (A) & the angle of minimum deviation (D). So, reason (R) is also correct.
