This new twist on the Michelson-Morley device measures the small differences in time needed for 2 separate light beams to trevel 2 different
paths,bouncing the beams back and recombining them. the different paths may be of different lengths or composed of different materials to create alternating interference fringes on a screen.Positioning the magnetic optical components on our metal base is easy and accurate.The
distance can be adjusted without a ruler as the base contais a permanent grid at a 45° angle.Unlike other models ,we include all parts needed
to measure the coefficient of linear expansion of a metal. Contains metal base with scale;optical components with magnets;3 rods:brass,aluminum,steel.
