Quantum Phy Flashcards
1
Q
photon
A
a discrete packet of energy of electromagnetic radiation
E of 1 photon = h x f
2
Q
evidence for behaviour of EM radiation
A
E-emission of electrons only when EM radiation is above a minimum frequency regardless of intensity
M-max KE of emitted electrons is affected by the frequency of EM radiation but is independent of intensity
3
Q
threshold frequency/wavelength
A
min frequency/ max wavelength of EM radiation to cause emission of electrons from the surface of a metal
