G'day all, my first post :)(adsbygoogle = window.adsbygoogle || []).push({});

I've recently been studying quantum physics (well the basics anyway) and I have come across parts I don't understand fully.

We define a photon as the discrete quantity (particle) of electromagnetic radiation. What I am trying to understand is exactly how to picture a photon. If it is a particle what is this frequency a measure of?

Through my study I've seen the need to introduce the photon to explain black body radiation as classical theory did not work. How exactly is this the case?

Thanks,

Jaguar
