Part C

The equation for photon energy, $E,$ is

$E=\frac{hc}{}$

where $h=6\mathrm{.}626{10}^{-34}J*s($Planck$\text{'}$s constant$)$ and $c=2\mathrm{.}99{10}^8\frac{m}{s}($the speed of light$).$

What is the wavelength, $,$ of a photon that has an energy of $E=3\mathrm{.}48{10}^{-19}J?$

Units

In Paris A through C$,$ the quantities were already given with the appropriate units. However, you should always determine which unit is most appropriate for each quantity, then do any necessary conversions before substituting numbers into the formula. Part D gives an example of this type of situation.
