Answer
The energy of a photon of that light is $3.734\times10^{-19}J$.
Work Step by Step
*Strategy:
To find the energy of a photon of that light requires the use of the following formula $$E=h\times\nu$$
$E$ : the energy of a photon of that light
$h$ : Planck constant ($h=6.626\times10^{-34}J.s$)
$\nu$ : frequency of that light
- Step 1: Find the known variables
We figure out the frequency of that light in part a): $\nu\approx5.635\times10^{14}s^{-1}$
- Step 2: Calculate the energy of a photon of that light
$E=h\times\nu=(6.626\times10^{-34})\times(5.635\times10^{14})\approx3.734\times10^{-19}J$.
