What is the refractive index of a material of prism if the frequency of light wave in it is \(3 \times 10^{14} \mathrm{~Hz}\). The wavelength of light in the material of prism is \(8000 Å\).
- A 0.225
- B 0.125
- C 2.25
- D 1.25
Answer & Solution
Correct Answer
(D) 1.25
Step-by-step Solution
Detailed explanation
The speed of light in a medium is given by the product of its frequency and wavelength. Let \(v\) be the speed of light in the material, \(f\) be the frequency, and \(\lambda\) be the wavelength. \(v = f \times \lambda\) Given \(f = 3 \times 10^{14} \text{ Hz}\) and…
