Planck's Law

Just checking but in Planck's Law the electromagnetic energy is in the form of quanta and quanta is also a photon right? Quanta and photon can be used interchangeably? They are the same thing?

Re: Planck's Law

Or what is the difference between quanta and a photon?

Re: Planck's Law

Quanta are packets of energy, while a photon is a packet of light from electromagnetic radiation, or a type of quanta. Both are forms of energy distilled into a "packet" and both imply that energy exists in discrete units. Quanta is just a broader term for all energy but a photon refers specifically to electromagnetic energy!

Re: Planck's Law

Hello

Can someone please explain to me what Pancks law means in terms of quanta and photons. Im confused.

Re: Planck's Law

Another way to think of it is that electromagnetic radiation isn't a single flow. It is made up of quanta of energy, the size of which involves Planck's constant.
