Which of the following statements about the photoelectron effect is NOT correct?

ID: 1553510 • Letter: W

Question

a. Photoelectrons produce a photocurrent when they travel to an electrode which has a positive potential compared to the metal surface.

b. The emission of photoelectrons is independent of the wavelength of the light used

c. The incident photon must have a certain minimum energy to cause a photoelectron to be emitted

d. The emission of photoelectrons can be stopped by applying a positive Stopping Potential to the metal surface

Correct option is (b)

When light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect.

The energy of the incident photon must be equal to the sum of the metal's work function and the photoelectron kinetic energy
