The refractive index of a particular material is \(1.67\) for blue light, \(1.65\) for yellow light and 1.63 for red light. The dispersive power of the material is
- A \(0.0615\)
- B \(0.024\)
- C \(0.031\)
- D \(1.60\)
Answer & Solution
Correct Answer
(A) \(0.0615\)
Step-by-step Solution
Detailed explanation
Given, refractive index for blue light, \(\mu_{b}=1.67\) Refractive index for yellow light, \(\mu_{y}=1.65\) Refractive index for red light, \(\mu_{r}=1.63\) Dispersive power, \(\omega=\) ? Dispersive power is the ratio of angular dispersion and mean deviation. The formula of…
