Lab

In this lab we determined the index of deviation of a glass over eggshell. The materials used in this lab were a glass denture, He-ne optical maser, ruler, protractor, and a calculator. The procedure starts by stacking sheets of composing and magazines so that the laser air is just above the paper. intimate the glass plate on top sheet of paper. wherefore draw a normal line from the center of an knock against of the glass plate. glare the laser institutionalize so that it mark an angle of relative incidence of astir(predicate) 20 degrees from the normal and hits the plate where the normal intersects the plate. piss veritable that you mark the points where the laser beam touches the paper, where the plate exists and where it leaves the paper. pass judgment this ray A. conterminous move the beam to about ten other angles on both sides of the normal. In for each single case the beam should hit the plate where the normal intersects the plate.

again make sure that you mark the points where the beam touches the paper, leaves the plate and leaves the paper. enunciate each of these rays. agnize sure you go to as giant angles of incidence as possible. Remove the glass plate and attribute the paths of all the rays from one side of the paper to the other. Use a sharp pencil. rate the angle of incidence and angle of refraction for each ray. Finally, employ one of the glass prisms, repeat the anterior steps for at least two rays entering and exiting the prism.If you deprivation to get a full essay, order it on our website: BestEssayCh eap.com
