Question

Differentiate between light sources that have 6500K as their colour

and correlated-colour temperatures, respectively.​

Answer 1

Explanation:

Temperature tells us how much atoms are jiggling around. It is, in a way, a characteristic energy of a system. The usual unit, the kelvin (K), is not usually thought of as a unit of energy, but we can turn it into one using the Boltzmann constant: kBT has units of energy. (this quantity does not in general have a physical interpretation, but it will be close-ish to the kinetic energy of the atoms)
