The task is to convert the given wavelength of 450 nm into energy in electron volts (eV) using the formula E = hc/\u03bb, where E is energy, h is Planck's constant, c is the speed of light, and \u03bb is the wavelength. The goal is to find the energy corresponding to the absorbed light, which is determined to be 2.76 eV."}
