1
Q
what were the results of the davison germer diffraction experiment?
A
the electrons showed a diffraction pattern, this tells us that electrons/ particles have wave-like properties
2
Q
what did the photoelectric effect show?
A
that waves have particle-like properties
3
Q
what is wave particle duality
A
it describes how particles act like waves and waves act like particles
4
Q
what does the atomic spectra tell us?
A
it tells us that only particular energy amounts are emitted and atoms only have particular energy levels, meaning that energy is quantized
5
Q

A
constructively
6
Q
when two out of phase waves add, they add?
A
destructively
