WAVE NATURE OF ELECTROMAGNETIC RADIATION

Continuous spectrum. This spectrum is due to dispersion of white light. Dispersion of white light gives VIBGYOR colors, on photographic plate, without any gap between each color. This type of spreading colors is called continuous spectrum. White light produced from sunlight, incandescent filament lamp, and solid, or liquids at high temperature gives incandescence. VIBGYOR means, violet, indigo, blue, green, yellow, orange, and red. Emission, emission, and absorption spectrum. Based on white light emission and absorption by gas or vapor. Spectra can be divided into two types. One. Emission spectrum to absorption spectrum. Emission spectrum, spectrum due to emission of white light by gas, a weapon at high temperature. It consists of bright lines and dark background. It is due to emission of energy by electrons. Absorption spectrum. Spectrum due to absorption of white light by gas and transmitted white light. It consists of dark lines on bright background. It is due to absorption of energy by electrons. Line and band spectrum based on spectral lines, spectra can be divided into two types. One. Line spectrum or atomic spectrum. Two. Ban spectrum. Line spectrum, or atomic spectrum, or discontinuous spectrum. It is characteristic of atoms. Example, hydrogen atom. It consists of distinct lines. It is due to excitation, and the excitation of electron in an atom. Emission and absorption spectra shows the line spectrum. Band spectrum, characteristic of molecules, example, H two molecule. It consists of closely spaced lines called bands. It is due to vibration and rotation of atoms in the molecule. Example, H two molecule. Hydrogen spectrum. The spectrum of hydrogen is the simplest of all spectra. Hydrogen atom, exhibits both emission as well as absorption spectra. In 1885, bomber first observed a series of bright lines in the visible region of hydrogen spectrum and these are called lines of Bama series. Later, other series of lines were identified. The lines of bomber series of hydrogen spectrum are cold as H alpha H beta H gamma for H alpha, N is equal to three. For H beta N is equal to four. So H gamma and is equal to 5. The wave number of the spectral line of hydrogen spectrum for any series is given by rydberg secretion. Nubar is equal to one by lambda that is equal to R into one by N one square minus one by N to square. Where R rydberg constant one lag 9677.8 centimeter inverse. And one and M two are a whole numbers hydrogen spectrum consists of 5 series. You can see the table for the details of each series like ear of discovery, spectral series, values of N one, and N two, spectral region, and wave number formula. Lyman series. Electron jumps from and two is equal to two, three, four, two, N one is equal to one. Electron jumps from N two is equal to three, four, 5, two, N one is equal to two. Passion series electron jumps from N two is equal to four, 5, 6, two, N one is equal to three. Bracket series. Electron jumps from end to is equal to 5, 6, 7, two, N one is equal to four. Fund series. Electron jumps from N two is equal to 6 7 8 two N one is equal to 5. See the above illustration to clearly understand the 5 series.
