A mirage seen on a stretch of road in hot weather. A prismatic periscope that is used in a submarine. A bundle of optical fibres that is used in endoscopes and telecommunications. A pair of spectacles that corrects myopia. 3 / 5 3) Which statement correctly describes the direction of the bending of light passing¬†into a material of higher optical density? Light travelling into a material of higher optical density will bend in a clockwise direction. Light travelling into a material of higher optical density will bend towards the normal. Light travelling into a material of higher optical density will bend away from the normal. Light travelling into a material of higher optical density will bend in an anticlockwise direction. 4 / 5 4) The refractive index of a material is 2.0. What is the speed of light in this material? 1.5 × 108 m s-1 3.0 × 108 m s-1 4.0 × 108 m s-1 2.0 × 108 m s-1 5 / 5 5) Which of the following does not involve total internal reflection?
