IB Physics SL S1.3.1 General Mathematics Questions question 1

[Maximum number: 1]

A group of students is investigating refraction in a semi-circular glass block.

Light from a ray box enters the curved side of the block. The light passes through the block and leaves, refracted, at P .

The students vary the position of the ray box to obtain data to determine the refractive index of the glass. They use a protractor to collect values for the angles of incidence θi\theta_{i} and refraction θr\theta_{r} at P and record them on a table.
