Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transition from the energy level n = 2 to the level n = 1. Description: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave). Wavelength is defined on the left below, as the distance between adjacent peaks (or troughs), and may be designated in meters, centimeters or nanometers (10-9 meters). A. 15. Visible lights mainly have the wavelengths of 400 to 700 nanometers. Wavelength and frequency are therefore inversely related. A second scientist measured the wavelength of a green light as #5.6 * 10^-7# meters. The variable c is the speed of light. Chemistry Questions.
