Question 69

Easy

A student investigates how light refracts as it passes from air into a plastic block. They measure angle $A$ (in air) and angle $B$ (in plastic) for several different trials. Figure 3 shows a graph of the student's results.

Figure 3: A line graph of angle B against angle A. The vertical y-axis is labeled 'Angle B (degrees)' and goes from 0 to 40 in grid increments of 5. The horizontal x-axis is labeled 'Angle A (degrees)' and goes from 0 to 60 in grid increments of 5. A straight line of best fit starts at the origin (0,0) and passes exactly through the points (15, 10), (30, 20), and (45, 30).

Use the graph to calculate a value for:

\frac{\text{angle } B}{\text{angle } A}
