The velocity of light is 3 $\times$ 10 $^{8}$ m/sec. Which value is closest to the wavelength in nanometer of a quantum of light with frequency of 8 $\times$ 10 $^{15}$ sec $^{- 1}$ ?
2.3 $\times$ 10 $^{7}$
5.4 $\times$ 10 $^{- 18}$
1.2 $\times$ 10 $^{- 2}$
37.5

$c = n λ$
$λ = \frac{c}{n} = \frac{3 \times 10^{8}}{8 \times 10^{15}} = 37.5 n m$
