The frequency of a photon associated with an energy of 3.31 eV is (given h=6.625×10−34 Js)0.8×10158.0×10151.6×10153.2×1015

energy =hν3.31eV=6.625∗10−34νν=3.31∗1.6∗10−196.625∗10−34 (∵e=1.6∗10−19C) =0.8∗1015Hz

The frequency of a photon associated with an energy of 3.31 eV is (given h $= 6.625 \times 10^{- 34}$ Js)

$0.8 \times 10^{15}$
$8.0 \times 10^{15}$
$1.6 \times 10^{15}$
$3.2 \times 10^{15}$

energy $= h ν$
$3.31 e V = 6.625 * 10^{- 34} ν$

$ν = \frac{3.31 * 1.6 * 10^{- 19}}{6.625 * 10^{- 34}}$ ( $∵ e = 1.6 * 10^{- 19} C$ )

$= 0.8 * 10^{15} H z$
