When you measure the absorption of light by a protein in solution, it is usually recommended to measure at absorption levels between 0.1 and 1 because, at higher than 1, the absorption is not linear with protein concentration, and below 0.1, the measurements are noisy and less reliable. The absorption coefficient of rhodopsin at 496 nm is 46000 M-cm-. If you have a 1 M solution of rhodopsin, how many times will you dilute the solution so that the diluted solution will give you an absorption reading at 496nm that is in the sensitive range? And what will be the absorption by the diluted solution?

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...
