Refractive index of the medium is ' \(\mu\) ' and wavelength is \(\lambda\), then which of th wing proportionality relation is correct?
- A \(\mu \propto \frac{1}{\lambda^{2}}\)
- B \(\mu \propto \lambda^{2}\)
- C \(\mu \propto \frac{1}{\lambda}\)
- D \(\mu \propto \lambda\)
Answer & Solution
Correct Answer
(C) \(\mu \propto \frac{1}{\lambda}\)
Step-by-step Solution
Detailed explanation
(A)
\(\mu=\frac{c}{v}=\frac{v \lambda_{0}}{v \lambda} \quad \therefore \mu \propto \frac{1}{\lambda}\)
\(\mu=\frac{c}{v}=\frac{v \lambda_{0}}{v \lambda} \quad \therefore \mu \propto \frac{1}{\lambda}\)
