WebExplanation: Red has the longest wavelength and violet has the shortest wavelength. Wtogether, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 40. WebJust as an observation, it seems that the bigger the energy level drop that the electron makes (nj to n=2), the higher the energy of the wave that is emitted by the electron. ex: n3 to n2 : red n4 to n2 : cyan etc But, the drop from n2 to n1 creates a wave with higher energy than n6 to n2 (122nm vs 410nm).
