6.99 The photoelectric effect can he 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 IR light. If the energy needed for signal generation is 3.5 × 10 − 20 J , what is the wavelength and frequency of light that barely can be detected?
