Which of the following best describes atomic absorption/emission?
Electrons absorb energy, making them jump from ground state to an excited state. This state is unstable, so the electron falls back to ground state, releasing light energy in the process.
Electrons absorb energy, making them jump to an excited state and releasing light energy in the process.
Protons absorb energy, making them jump from ground state to an excited state. Excited state is unstable, so the proton falls back to ground state, releasing light energy in the process.
Protons absorb energy, making them jump to an excited state and releasing light energy in the process.

Electromagnetic energy is radiation that travels in waves
All electromagnetic radiation moves at the speed of light
low frequency = high energy
high frequency = high energy
low wavelength = high energy
