Wavelength is commonly designated by the Greek letter lambda (Î»). The concept can also be applied to periodic waves of non-sinusoidal shape. The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.here L is the slit width, R is the distance of the pattern (on the screen) from the slit, and Î» is the wavelength of light used. The function S has zeros where u is a non-zero integer, where are at x values at a separation proportion to wavelength.
Best Answer: Energy = hc/lambda, where h = Planck's constant = 6.626 x 10^-34 Js, c = the speed of light = 3.00 x 10^8 m/s, and lambda = wavelength in m. 164 kJ/mole means that we are dealing with 6.022 x 10^23 molecules of 11-cis-retinal, not just one molecule.So, let's just deal with one molecule.he human eye contains a molecule called 11-cis-retinal that changes conformation when struck with light of sufficient energy. The change in conformation triggers a series of events that results in an electrical signal being sent to the brain. The minimum energy required to change the conformation of 11-cis-retinal...
