Question 36
Easy

A student plotted the results of an investigation into the refraction of light travelling from air into a semi-circular plastic block.

A graph grid showing 'Angle of refraction, r / °' on the vertical y-axis ranging from 0 to 50 with major grid lines every 10 units and minor grid lines every 2 units, and 'Angle of incidence, i / °' on the horizontal x-axis ranging from 0 to 80 with major grid lines every 10 units and minor grid lines every 2 units. Eight data points are plotted at: (10, 7), (20, 13), (30, 19), (40, 25), (50, 31), (60, 36), (70, 40), and (80, 43).

Draw a curve of best fit through the plotted points on the graph.
