The photoelectric effect can be used in engineering designs for practical applications. For example, infrared goggles used in night-vision applications have materials that give an electrical signal with exposure to the relatively long wavelength of IR light. If the energy needed for signal generation is 2.0 x 10-20 J, what is the minimum wavelength? What is the frequency of light that can be detected?
