A student performs an experiment to determine the index of refraction n of a rectangular glass slab in air. She is asked to use a laser beam to measure angles of incidence 8, in air and corresponding angles of refraction 6, in glass. The measurements of the angles for five trials are given in the table below. Trial 0, 0, 30° 20° 40° 50⁰ 32" 60⁰ 37" 5 70° 40° (a) Complete the last two columns in the table by calculating the quantities that need to be graphed to provide a linear relationship from which the index of refraction can be determined. Label the top of each column. (b) On a printout of the grid below, personal graph paper or excel, plot the quantities calculated in (a) and draw an appropriate graph from which the index of refraction can be determined. Label the axes. Using the graph, calculate the index of refraction of the glass slab. 2- 1 2 تر 4 27
