Question

How would the number of electrons or the energy level the electrons are in affect the color of the light emitted?

Answer 1

`E = hf`

Explanation:

`E` is the difference in energy level of the electron.

`f` is the frequency of the EM radiation, which is related to the color if it falls in the visible part of the spectrum.

`h` is the Planck's constant, which is named after the guy who created this equation.
