The minimum frequency оf electrоmаgnetic rаdiаtiоn required to eject electrons from the surface of potassium metal in a vacuum corresponds to electromagnetic radiation with a wavelength of 554 nm. Suppose that we irradiate the potassium sample with 556 nm light. Answer the following questions: (a) Is possible to detect electron photocurrent in the photoelectric current experiment? (b) What would happen if radiation wavelength changes to 558 nm?(c) What would happen if radiation wavelength changes to 550 nm?
