Application +4 | -1

Monochromatic light of wavelength

600 \mathrm{~nm}

is incident from air on a glass surface (refractive index of glass is

1.5

). The speed of the refracted light will be

View answer and explanation

Correct option: C

2 \times 10^{8} \mathrm{~ms}^{-1}

Option C (

2 \times 10^{8} \mathrm{~ms}^{-1}

) is correct because the speed of light in a medium is the speed of light in vacuum divided by the refractive index of the medium.
