# Problem: Calculate the energy, in electron volts, of a photon whose frequency is the following.2.60 GHz____ eV

###### FREE Expert Solution

Photon energy:

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

1GHz = 109Hz

1eV = 1.6 × 10-19

f =  2.60GHz(109Hz/1GHz) = 2.60 × 109 Hz
