Question
The following statements are regarding the Photoelectric effect experiment setup above PheT simulation. Indicate that each statement is true (T) or false (F). Give; a brief reasoning for your answer. The energy of the photons hitting tire plate are all equal at a fixed wave length. The force that makes the electron pop out of the metal plate is exerted by the battery. In order to have electrons emitted front natal plate, the energy of photon must be equal to or more than the work function of the metal. Different metals have different work function values. The electrons emitted with the largest initial kinetic energy are those that were the least lightly bound in the metal.Explanation / Answer
a) True
Energy of photon, E = h*c/lamda
if the photons have same lamda, they have same energy as well.
b) Flase.
It is done by photon.
c) True.
If the photon has less energy than work function it can not take out the elctron from the metal.
d) True.
work function is diffrent for diffrenet materials.
e) True.
If an electron loosly bound to the elctron will gain more gain kinetic energy.
