Question

What is the relationship between energy frequency and wavelength?

Answer 1

Answer:

The energy $E$ of a photon is given by:

$E=h\nu$ (1)

Where:

$h$ is the Planck constant

$\nu$ is the frequency

On the other hand, there is an inverse relation between the frequency and the wavelength $\lambda$:

$\nu=\frac{c}{\lambda}$ (2)

Where $c$ is the speed of light, which is also a constant.

If we substitute (2) in (1) we will have the following:

$E=h\frac{c}{\lambda}$ (3)

This means, there is direct relation between the energy and the frequency and there is an inverse relation between the energy and the wavelength.
