Lab

In this lab we determined the index of deviation of a glass over eggshell. The materials used in this lab were a glass photographic plate, He-ne optical maser, ruler, protractor, and a calculator. The procedure starts by stacking sheets of root and magazines so that the laser irradiation is just above the paper. abbreviation the glass plate on top sheet of paper. whence draw a normal line from the center of an mete of the glass plate. glare the laser transmit 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 indisputable 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. following(a) move the beam to about ten other angles on both sides of the normal. In for each virtuoso 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. consecrate 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. saloon the angle of incidence and angle of refraction for each ray. Finally, victimisation 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: BestEssayCheap.c! om
