Monochromatic light of frequency 5·0 × 10¹⁴ Hz passes from air into a medium of refractive index 1·5. Find the wavelength of the light (i) reflected, and (ii) refracted at the interface of the two media.
A ray of light is incident on a surface separating air from a denser medium A of refractive index μ₁. It is then made incident on the parallel surface of another medium B of refractive index μ₂ at the same angle of incidence. If the angle of refraction in the two media are 30° and 35° respectively, then in which one of the two media (A or B) will light travel faster and why ?
