Spectral Flatness $65.33 Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Spectral flatness or tonality coefficient is a measure used in digital signal processing to characterize an audio spectrum. Spectral flatness, measured in decibels, provides a way to quantify how tonelike a sound is, as opposed to being noiselike. The meaning of tonal in this context is in the sense of the amount of peaks or resonant structure in a power spectrum, as opposed to flat spectrum of a white noise. A high spectral flatness indicates that the spectrum has a similar amount of power in all spectral bands this would sound similar to white noise, and the graph of the spectrum would appear relatively flat and smooth. A low spectral flatness indicates that the spectral power is concentrated in a relatively small number of bands this would typically sound like a mixture of sine waves, and the spectrum would appear spiky.

Hubble COS Instrument
Help with Rydberg Equation!?
An astrophysicist working at an observatory is interested in finding clouds of hydrogen in the galaxy. Usually hydrogen is detected by looking for the Balmer series of spectral lines in the visible spectrum. Unfortunately, the instrument that detects hydrogen emission spectra at this particular observatory is not working very well and only detects spectra in the infrared region of electromagnetic radiation. Therefore the astrophysicist decides to check for hydrogen by looking at the Paschen series, which produces spectral lines in the infrared part of the spectrum. The Paschen series describes the wavelengths of light emitted by the decay of electrons from higher orbits to the n=3 level.
What wavelength lambda should the astrophysicist look for to detect a transition of an electron from the n=6 to the n=3 level?
Thanks for your help!
1/wavelength = R( 1/n_1^2 - 1/3^2) where R is the Rydberg constant in units of inverse length.
