Give It Some Thought 6.3

Part A

In the figure below, will the kinetic energy of an emitted electron equal the energy of the photon that causes its emission?

In the figure below, will the kinetic energy of an emitted electron equal the energy of the photon that causes its emission?

The kinetic energy of an emitted electron will be lower than the energy of the photon that causes its emission. The kinetic energy of an emitted electron will be higher than the energy of the photon that causes its emission. The kinetic energy of an emitted electron will equal the energy of the photon that causes its emission. Photon hits surface with energy hv Electrons emitted from surface by energy of photon Metal surface The photoelectric effect

Explanation / Answer

Ans: A

Energy of electron emitted from the surface of metal (hv) = E – hv0

Where,

hv = Energy of emitted electron = kinetic energy of electron

E = energy of photon

hv0 = Threshold energy or minimum energy required to release the electron from the metal surface ()
