# Finding wave wquations for photons

## Homework Statement

Use the relativistic expression for energy E^2=p^2c^2+(m_0)^2(c)^4 to find a wave equations for photons. Find a solution for ψ and compare to the electric field (hint: photons are massless, E_op=ih(d/dt) and p_op=h/i(d/dx)

## Homework Equations

the only equations i know are the ones given in the problem

## The Attempt at a Solution

if somebody could please point me in the right direction, i do not have the mental power to understand what i should even try to do first. Thanks for any help you can provide.

Photons are quanta of fields, it doesn't really work the way your problem suggests.

The differential equation for the quantized electromagnetic field is obtained by applying a canonical quantization* to the classical electrodynamic equation for the one-forms describing the field at a classical level.

* very tricky issue.

Okay, if E_op=ih(d/dt), then what would E_op2 be?

I fail to see how that is helpful.
