To determine the wavelength of mercury light using diffraction grating and spectrometer. The telescope is brought in line with the collimator
The telescope is brought in line with the collimator. 2) Setting up the grating … This video gives a basic understanding of using spectrometer for finding the wavelength of light spectrum from visible source of light. Apparatus usedDiffraction grating, spectrometer, mercury lamp, sprit level and reading lens. 3. A grating disperses light of different wavelengths to give, for any wavelength, a narrow fringe. A mercury lamp is used as the light source, and the diffraction pattern is observed using a spectrometer. Using more expensive laser techniques, it is possible to create line densities of 3000 lines/mm or higher. In this experiment a spectrometer equipped with a diffraction grating is used to identify spe-cific wavelengths from the emission spectrum of mercury, to measure these wave-lengths precisely, and … In this lab, you will use a spectrometer to study diffraction from a grating and measure the wavelengths of certain lines in the spectrum of different lamps including a mercury arc lamp. The angles of … - 1 - EXPERIMENT NO. The document describes using a diffraction grating and spectrometer to determine the wavelengths of light emitted by a mercury vapor lamp.
