Scientists are studying ways to improve the efficiency of solar cells by studying a process called photon unconversion . In this process , the energy of two can become combined to form a new photon n energy equal to the sum of the two combined ns With this process, abundant infrared radiation са converted into visible light that can be used by SE to produce electricity . Suppose an infrared n with a wavelength of 853 nm were combined nother infrared photon with a wavelength of 935 hat would be the wavelength of the new photon, in nm?
