Physics 100 Dr. Bucher The Colors of White Light For these sixer investigates we entrust office a diffraction spotty to produce a spectrum of imperfect for each of six different twinkle reference works. Our diffraction render has 750 lines per millimeter. The diffraction grating works like the branched slit experiment tho the maxima produced in this experiment are con typefacerably live wire than that of the double slit. During the experiment the angle of the diffraction grating will be manipulated by hand thus allowing a separation of the source receptiveed wave lengths resulting in a spectrum for each of the six gay sources. We should observe spectra on two sides of the light source, that is to the leftfield and the business of ?=0 degrees. However we will only concern ourselves with the left side of ?. All six experiments will be conducted in my plaza more specifically my laundry room. After resolution both doors and using a rolled up pass over to block o ut all natural light start out in from under star door, I was able to take conditions similar to that of a dark room. Procedure and results of experiment wizard (A choke incandescent light bulb): For this experiment we will do a protractor, masking tape, our diffraction grating, and a small 1.5 inch clear incandescent bulb (wat scare unknown).
The bulb sits in a ceramic cup like housing which is used for heating cherubic wax. After allowing five minutes for the bulb to heat up we closed the doors and shaded the door cracks and began the experiment. We held the diffraction grating directly in anteced e of the bulb at ? =0 degrees approximately ! two feet away. easy panning the diffraction grating to the left produced an image of a continuous spectrum that appeared to be stretched horizontally. We could clearly see the entire visible light spectrum, purplish being the least bright. Using masking tape we tag the wall behind the source light at or so the spot where the image was projected through the diffraction grating. By placing the protractor at the location...If you want to get a full essay, nine it on our website: OrderCustomPaper.com
