Question

7. Monochromatic light of wavelength 500 nm is incident from air to glass. What is the wavelength of light in glass. The refractive index of glass is 1.5.




​

Answer 1

Answer:

333.3 nm.

Explanation:

Wavelength X = 500 nm = 500 × 10-9 m Refractive index of the glass n = 1.5

2×10⁸/6×10¹⁴ = 3.333 x 10-⁷ m = 333.3 nm.
