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 835 nm, what would be the wavelength of the new 'combined' photon, in nm?

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.
