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. Light travelling into a material of higher optical density will bend in a clockwise direction. 2 / 5 2) What is the refractive index of a medium? the ratio of the speed of light in vacuum to the speed of light in the medium. the ratio of the speed of light in the medium to the speed of light in vacuum. the ratio of the speed of light in the medium to the speed of light in air. the ratio of the speed of light in air to the speed of light in the medium. 3 / 5 3) What is the approximate value of the refractive index of glass? 1.0 1.3 1.5 2.4 4 / 5 4) Which of the following is not an effect of refraction? A ray of light changes direction as it travels through an optical fibre. A rainbow is observed when a ray of light passes through a glass prism. A straight pencil appears to be bent when partially submerged in water. A fish appears bigger than its actual size to an observer above water. light changing direction in an optical fibre is due to TIR. 5 / 5 5) Which of the following does not involve the phenomena of total internal reflection of light rays? A bundle of optical fibres that is used in endoscopes and telecommunications. A mirage seen on a stretch of road in hot weather. A prismatic periscope that is used in a submarine. A pair of spectacles that corrects myopia. Your score is Restart quiz
