List the 4 main points of the laws governing radiation

A law is used to describe a body of observations, and when studying radiation there are four:

Planck's Law

This law states that every object emits radiation over the entire electromagnetic spectrum.  That means that you emit radiation at all wavelengths, and so does everything around you.

Wein's Law

It states that the wavelength of peak emission is inversely proportional to the temperature of the emitting object.

Stefan–Boltzmann Law

This law states that the total amount of energy per unit area emitted by an object is proportional to the 4th power of the temperature.

Kirchhoff's Law

This law states that for an object whose temperature is not changing, an object that absorbs radiation well at a particular wavelength will also emit radiation well at that wavelength.

just finished this it is b. centrifugal force

i dont know the answer sorry but if i knew it i would of told you
