Question

Electrons are capable of emitting energy in the form of light at very narrow ranges of wavelengths. These wavelengths can be measured to find the electron's
a. mass.
b. density.
c. energy level.
d. specific heat.

Answer 1

C. Electrons release photons at different energy levels which would tell us which level they are on.

Answer 2

The correct answer is (C) energy level.

The explanation:

When the electrons release photons , and those photons are at different levels

of energy . So we can define the electron's energy level from this photons which

tell us the energy level they are on.
