Hydrogen Spectrum
erge because the bigger the jump the higher the frequency.There can be two types of line spectrums, emission spectra and absorptions spectra.When an "excited" electron (an electron that has absorbed a ... hoton) jumps from a higher energy level to a lower energy level it releases photons, this is called emission. This happens when light passes through a hot gas and a prism:When an electron jumps from a ...

Fluorescence study of dyes
lyse the fluorescence spectra.For fluorescence spectra, there are two kinds, the excitation and the emission spectrum.The excitation spectrum is obtained by measuring the intensity of the emission as ... intensity of the emission as the excitation wavelength is altered by scanning a monochromator. The emission spectrum is obtained by measuring the emission intensity as a function of wavelength for ex ...
