Solve the all parts of given question:
Question: In an experiment on the photoelectric effect, a metal is illuminated by light. Electrons are emitted when the light's wavelength is less than 670 nm.
Part A: What is the metal's work function?
Part B: If light with a wavelength of 500 nm is used, what is the maximum kinetic energy of the emitted photoelectrons?
I need help to find the maximum kinetic energy of the emitted photoelectrons.
