Scientists are studying ways to improve the efficiency of solar cells by studying a process called photon upconversion. In this process, the energy of two photons can become combined to form a new photon with an energy equal to the sum of the two combined photons. With this process, abundant infrared radiation can be converted into visible light that can be used by solar cells to produce electricity. Suppose an infrared photon with a wavelength of 853 nm were combined with another infrared photon with a wavelength of 875 nm, what would be the wavelength of the new 'combined' photon?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
