The Balmer Rydberg equation explains the line spectrum of hydrogen. Find the de Broglie wavelength and momentum of the electron. Calculate energies of the first four levels of X. It's continuous because you see all these colors right next to each other. However, all solids and liquids at room temperature emit and absorb long-wavelength radiation in the infrared (IR) range of the electromagnetic spectrum, and the spectra are continuous, described accurately by the formula for the Planck black body spectrum. Line spectra are produced when isolated atoms (e.g. The existences of the Lyman series and Balmer's series suggest the existence of more series. The discrete spectrum emitted by a H atom is a result of the energy levels within the atom, which arise from the way the electron interacts with the proton. In an amazing demonstration of mathematical insight, in 1885 Balmer came up with a simple formula for predicting the wavelength of any of the lines in atomic hydrogen in what we now know as the Balmer series. (a) Which line in the Balmer series is the first one in the UV part of the spectrum? What will be the longest wavelength line in Balmer series of spectrum of hydrogen atom? Lines are named sequentially starting from the longest wavelength/lowest frequency of the series, using Greek letters within each series. [1] There are several prominent ultraviolet Balmer lines with wavelengths shorter than 400nm. It has to be in multiples of some constant. Direct link to Andrew M's post The discrete spectrum emi, Posted 6 years ago. This is indeed the experimentally observed wavelength, corresponding to the second (blue-green) line in the Balmer series. Nothing happens. This corresponds to the energy difference between two energy levels in the mercury atom. So if an electron went from n=1 to n=2, no light would be emitted because it is absorbing light, not emitting light correct? If it happens to drop to an intermediate level, not n=1, the it is still in an excited state (albeit a lower excited state than it previously had). The frequency of second line of Balmer series in spectrum of `Li^( +2)` ion is :- In an electron microscope, electrons are accelerated to great velocities.
