Study and Analysis of Atomic Spectra (original) (raw)
2020, International Journal of Scientific and Research Publications (IJSRP)
When we look at objects giving off light (or reflecting light) we find three types of spectra. They are produced in different ways, and can actually tell us about the physical properties of the materials producing the spectra. These spectra are known as "a continuous spectrum" (or continuum emission), "an emission line spectrum" and "an absorption line spectrum". Here, in this project we have tried to analyze all these spectra obtained from common light sources and KMnO 4. All the spectra were obtained with the help of a diffraction grating & spectrometer. Later, the spectra corresponding to different wavelengths and energy levels were observed. The electronic transitions and material involved in the formation of spectra were found out. Also, the wavelength of the light emitted, absorbed by a specific light source or molecule was determined along with the vibrational energy level of phosphor coating and energy lost in collision in case of a CFL.
