Planck's Law

[Savannah Mance 4G]

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?

Or what is the difference between quanta and a photon?

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!

Hello

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

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.
