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 ...
