What Does P Represent in Intensity = P/Area?

[Maddie1609]

Hello!

I just started learning about Stefan-Boltzmann's law and I'm stuck on the word for P in Intensity = P/Area.

Also, does anyone have a quick and easy explanation for how Max Planck started quantum mechanics by saying energy is quantized and how the equation E = nhf says so?

How about Power!
