Given small samples of three liquids, you are asked to determine their refractive indexes.
However, you do not have enough of each liquid to measure the angle of refraction for light
refracting from air into the liquid. Instead, for each liquid, you take a rectangular block of
glass (n = 1.52) and place a drop of the liquid on the top surface of the block. You shine a
laser beam with wavelength 638 nm in vacuum at one side of the block and measure the
largest angle of incidence for which there is total internal reflection at the interface between
the glass and the liquid (Figure 1). Your results are given in the table the table below.
