Q

Where does electromagnetic radiation come from?

A

When an atom absorbs energy, the electrons jump to a higher energy level, but can’t stay at this higher level forever. When the electron falls back to its ground state, a photon of electromagnetic radiation is emitted

Q

What is Heisenberg uncertainty principal

?

A

We can only know a probability of where an electron might be. Instead, the are most likely in orbitals, we just don’t know where they are in the orbital.
