1. How many lines would be in the emission spectrum of hydrogen if the hydrogen atom had only 4 energy levels? 2. What was the initial energy level of an electron if it was excited by a photon of wavelength 0.656µm and jumped to an energy level of 3? 3 .Calculate the frequency of visible light emitted by electron drop from n=233000 in Balmer series of hydrogen atom.
When an electron of an excited hydrogen atom descends, from an initial energy level (ni) to...
When an electron of an excited hydrogen atom descends, from an initial energy level (ni) to a lower (nf), characteristic electromagnetic radiation is emitted. The Bohr model of the H-atom allows the calculation of ?E for any pair of energy levels. ?E is related to the wavelength (?) of the radiation according to Einstein's equation ( ?E = [(hc)/?]). Distinct series of spectral lines have been classified according to nf: Lyman series:nf=1 (91<?<123 nm; near-UV). Balmer series:nf=2 (365<?<658 nm; visible)....

Electronically excited hydrogen emits in the visible part of the spectrum in a series of lines known as the Balmer series. Each of these transitions terminates in the n=2 level of hydrogen. What is the energy and wavelength and upper state quantum number for the first four of these transitions starting with the longest wavelength emission?

Item 4 Learning Goal: To calculate the wavelengths of the lines in the hydrogen emission spectrum Atoms give off light when heated or otherwise excited! The light emitted by excited atoms consists of only a few wavelengths, rather than a full rainbow of colors. When this light is passed through a prism, the result is a series of discrete lines separated by blank areas. The visible lines in the series of the hydrogen spectrum are caused by emission of...
