# What determines the frequency of photons?

May 16, 2017

#### Explanation:

The energy of the photon determines its frequency , the higher its frequency more is its energy , in terms of mathematics

$E = \frac{h c}{\lambda}$

and
here $\nu$ is frequency
$\lambda = \frac{c}{\nu}$
so substituting we get
$E = h \nu$
$E \propto \nu$
