Diffraction Grating Group 2 Members; ID# Dwayne Williams 0901509 Aeon Forbes 0804118 Lecture: sink Nelson sample design: 7 Experiment Date: October, 27, 2009 Experiment Title: Diffraction Grating Aim: To strike the mercury spectrum and to mathematical function the wavelength corresponding to the observed lines to calculate the space of the grating. Apparatus: spectrometer; Telescope, Collimator, Grating, Prism, table and Mercury lamp. Diagram: [pic] Results: shelve showing wavelength and drop dead for first and second do colours. put up | tinge |Type |Left |Right |Total angle |[pic]/m |sin( | | First Order | imperial | Moderate | 0 | 14.3 | 14.3 | 405 | | | | Violet | wishy-washy | 14.0 | 14.4 | 14.2 | 408 | | | | Violet | hale | 14.1 | 15.5 | 14.8 | 436 | | | | Blue fleeceable | listless | 17.0 | 17.5 | 17 | 492 | | | | Green | pissed | 19.0 | 19.5 | 19.

The device usually consists of thousands of narrow, closely spaced total slits, from which heat is propagated and different colours that contain in the light are observed. Visible light waves are the only electromagnetic waves that can be seen; Visible light is made up of various colours...If you want to get a full essay, regulate it on our website: BestEssayCheap.com
