(a) Briefly explain what is meant by the following terms: refraction, refractive index, angle of incidence, angle of refraction. [4 marks] (b) The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (i), (ii), and (iii), the angle of incidence is 55°; for case (iv), the angle of incidence is 0°. Identify which cases are incorrectly drawn and determine...
