This states the emission of electrons when electromagnetic radiation falls on an object or simply when a light particle knocks loose electron using enough energy.
After photon hits an electron, its resulting wavelength will be apparently:
shorter than the original
parallel with the original
longer than the original
perpendicular with the original
The needed components to have a 'photoelectric effect' are? (choose answers as much as possible):
During Compton effect, the photon particle doesn’t have kinetic energy because of what possible reason?
hint: KE = mass x velocity
During Photoelectric effect, what law can be applied when it deals with energy?
Newton 3rd law of motion
law of conservation of energy
law of gravity
It is the minimum energy needed to free the most weakly bound electron from the metal during Photoelectric effect.
photon max energy
What is the work function of/on a metal?
One (1) electrovolts (eV) is equals to:
1.32 x 10 -9 J
1.6 x 10 -11 J
1.6 x 10 -19 J
1.6 x 10 -34 J
The momentum of photon if represented by equation would be:
ρ = h x (wavelength)
ρ = hc / (wavelength)
ρ = hc / f
ρ = h / (wavelength)
How is the threshold frequency (work function) related to the photoelectric effect?
(choose as many correct answer as you can)
It is the maximum frequency of incident radiation needed to cause the ejection of atoms from anode
It is the minimum frequency of incident radiation needed to cause the ejection of electrons from the cathode
It is the minimum frequency of incident radiation needed to cause the ejection of atoms from anode
It is the frequency of incident radiation below which electron will be ejected from atom
