Hydrogen Spectrum

Isaac Newton discovered that when discolour light travels through a prism, a rainbow appears, this is called a spectrum. ane is usually taught that the spectrum contains 7 change: red, orange, yellow, green, blue, indigo and violet. besides in reality in that prise ar hardly 6 (indigo does not exist). The colors of the spectrum really crack to the varied wavelengths of light. When the antithetical wavelengths travel through the prism they sour at variant angles. This is a continuous spectrum. But there is also a diametrical spectrum called the line spectrum. The enthalpy spectrum is a line spectrum. Lines of slanted light, which represent the wavelength, are inclined despatch when atoms gain or loose zippo. Light carries faculty, photons. severally photon has a specific wavelength and aptitude quantity. When an atom gains muscle, this is called excitation, the change in energy, produces light. When a high emf is applied to hydrogen, it pulls the negatrons of the atom obscure and leaves fag end a positive ion, leaving merchant ship empty electron slashs. whence the electrons remaining can learn in which shell to go in. When they set off into a shell they loose energy. This scathe of energy gives out light.

The electron shells are equivalent to energy aims; each energy level have an exact frequency, and then a fixed energy level which therefore proclaim that the electron can only give off a fixed amount of energy. This is wherefore we choose the different colors. The lines in the spectrum represent the transition in energy levels. The lines of the spectrum converge as the frequency increases. The hydrogen spectrum is do up of 3 different series: the visible, ultra-violet infrared. Energy level converge because the bigger the bear the higher the frequency. There can be two types of line spectrums, galvanic arc spectra and absorptions... If you want to get a full essay, coiffure it on our website: Orderessay
