Green light of wavelength $5460 \overset{˚}{A}$ is incident on an airglass interface. If the refractive index of glass is $1.5$ , the wavelength of light in glass would be $(c = 3 \times 1 0^{8} ms^{- 1})$

Options:

Answer:

Solution:

$a^{λ} g = \frac{λ _{a}}{μ} = \frac{5460}{1.5} = 3640 \overset{˚}{A}$
