Blue light travelling in a vacuum has a wavelength of It enters a medium whose refractive index is What is its frequency in the medium?
(Speed of light in vacuum )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
The wavelength of blue light is, λ=450×10-9 m and the refractive index, n=1.5, the relation between refractive index and wavelength, λ1λ2=n2n1⇒450λ2=1.51⇒λ2=300 nm, then the frequency of refracted light is,…
