# Problem: Calculate the energy, in electron volts, of a photon whose frequency is the following.630 THz____ eV

###### FREE Expert Solution

Photon energy:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{h}}{\mathbf{f}}{\mathbf{=}}\frac{\mathbf{h}\mathbf{c}}{\mathbf{\lambda }}}$

1THz = 1012Hz

1eV = 1.6 × 10-19

f =  630THz(1012Hz/1THz) = 630 × 1012 Hz
