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). WebThe main difference is that the 395 nm LED emits much more visible light than the 365 nm LED. The 395 nm LED emits a pronounced violet-colored light, while the 365 nm LED emits a dull, bluish-white light (the result of residual light energy that "tails" off into the visible spectrum). Both types emit in the UV-A wavelength range and are ...
