601-Quiz

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.

• bernoulli effect

• photoelectric effect

• compton effect

• scatter effect

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):

• light source/photon

• electron

• work function

• kinetic energy

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 3^rd law of motion

• law of conservation of energy

• law of gravity

• Avogadro’s law

It is the minimum energy needed to free the most weakly bound electron from the metal during Photoelectric effect.

• photon max energy

• kinetic frequency

• intercepting energy

• work function

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
