We know that photon energy is given as
$E = h v$
$v = \frac{E}{h}$
Substituting the values results in
$v = \frac{0.1 \times 1.6 \times 10^{- 19} J}{6.626 \times 10^{- 34} J s}$
$= 2.415 \times 10^{13}$ Hz

Solution for (b)
The maximum photon wavelength is
$λ = \frac{h c}{E}$
By substituting the values provided,
$λ = \frac{(6.626 \times 10^{- 34} J s) (3 \times 10^{8} \frac{m}{s})}{0.1 \times 1.6 \times 10^{- 19} J}$
$= 1.24 \times 10^{- 5} m$
