Question

Suppose you are setting up the photoelectric effect experiment using the apparatus we went over in the class. Which of the following changes to the experiment could increase of the maximum initial kinetic energy of the ejected electron? Select all that apply and give a brief reasoning for your choices. For Problem 1 and 2, do not consider the ejected electrons due to the heating. Only the electrons ejected instantaneously as soon as the light hits the metal plates should be taken into account. Increasing the intensity of the light beam Decreasing the intensity of the light beam Increasing the wavelength of light Decreasing the wavelength of light Increasing the frequency of light Decreasing the frequency of light Increasing the voltage of the battery Decreasing the voltage of the battery Replacing the target with a material that has a larger work function Replacing the target with a material that has a smaller work function Which of the changes listed in Problem 1(a) - (j) can increase the number of electrons (i.e. increased current)? Select all that apply and give a brief reasoning.

Explanation / Answer

D.decreasing wavelength means increasing energy of incident light wave as energy is inversily proportional wave length.

E. Energy directly proportional to frequency

2.Number of electrons ejected can be increased by Increasing Intensity of light
