CSEC Physics · January 2017 · Paper 2 · Question 4(b)(ii)

A glass prism, as shown in Figure 4, may be used to produce a spectrum.

On Figure 4 above, trace the path of the white light into and out of the prism indicating the red ray and the violet ray.

This question uses a figure or table from the paper — you'll see it when you practise.
