1 Light changes direction when it travels from one medium to another due to changes in speed.
Imagine a ray of light entering a glass block at an angle.
a A ray of light hits a glass block at an angle of incidence of 35°.
i Draw a diagram showing the setup with a ray box, a glass block, and a normal line. Label the
angles of incidence and refraction clearly. (1 mark)
b The refractive index of glass is 1.5. Light bends as it slows down when entering the denser
medium.
i Calculate the speed of light in glass based on this refractive index. (2 marks)
