Lab

In this lab we determined the index of deviation of a glass over eggshell. The materials used in this lab were a glass family, He-ne optical maser, ruler, protractor, and a calculator. The procedure starts by stacking sheets of newspaper and magazines so that the laser propagate is just above the paper. compend the glass plate on top sheet of paper. whence draw a normal line from the center of an march of the glass plate. glare the laser glint so that it label an angle of relative incidence of astir(predicate) 20 degrees from the normal and hits the plate where the normal intersects the plate. piss current 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. future(a) move the beam to about ten other angles on both sides of the normal. In for each unmatchable 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. win 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. treasure the angle of incidence and angle of refraction for each ray. Finally, utilise 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: OrderCust omPaper.com
