Q10.
(a) Ice has an absolute refractive index of 1.31. Given that the
speed of light in a vacuum is c = 3 x 108 m/s, calculate the speed
of light in ice. (1 mark)
(b) A ray of light passes from air into ice at an angle of
incidence of 55 degrees., Calculate the angle of refraction,
assuming that air has an absolute refractive index of 1. (2
