Question

The frequency of a light wave in a material is 2 × 1014 Hz and wavelength is 5000 mathringA. The refractive index of material will be (A) 1.50 (B) 3.00 (C) 1.33 (D) 1.40

Refractive index μ=( c / v )=( c / v λ) = (3 × 108/2 × 1014 × 5000 × 10-10)=3

Q. The frequency of a light wave in a material is $2 \times 10^{14} Hz$ and wavelength is $5000 \overset{˚}{A}$ . The refractive index of material will be

1.50

3.00

1.33

1.40

Refractive index $μ = \frac{c}{v} = \frac{c}{v λ}$
$= \frac{3 \times 1 0 ^{8}}{2 \times 1 0 ^{14} \times 5000 \times 1 0 ^{- 10}} = 3$
