Why was Maxwell’s addition of the displacement current so

important?

Use Maxwell’s equations to solve for the speed of light.

A cadmium photodetector has a work function of 6.52 × 10−19 J.

What is the minimum wavelength of a photon required to eject a

photoelectron from the detector? What happens if the energy of the

photon is increased? What happens if two photons of the minimum

required energy are incident on the detector? What does this suggest about irradiance versus wavelength?
