Figure 9, shows the cross-section of an optical fibre made of two types of glass A and B. The refractive index of B is lower than that of A.
A ray of light enters the optical fibre at P and emerges from Q.
(i) Sketch the path of the ray through the fibre.
(ii) State the reason why light travels through the fibre as in (i) above.
