The value of Planck's constant is $6.63 \times 10^{- 34} J s$ . The speed of light $3 \times 10^{17} n m s^{- 1}$ . Which value is closest to the wavelength in nanometer of a quantum of light with frequency of $6 \times 10^{15} s^{- 1}$ ?
$10$
$25$
$50$
$75$

$v = \frac{c}{λ}$
$∴ λ = \frac{3 \times 10^{17} n m s^{- 1}}{6 \times 10^{15} s^{- 1}} = 50 n m$

The value of Planck's constant is 6.63×10−34Js. The speed of light 3×1017nms−1. Which value is closest to the wavelength in nanometer of a quantum of light with frequency of 6×1015s−1?10255075

v=cλ∴λ=3×1017nms−16×1015s−1=50nm
