Please add some details. 03 Refraction - Revision Quiz Test your understanding of Refraction here: 1 / 5 1) Which of the following does not involve total internal reflection? Raised virtual images under glass blocks. Images viewed through prism periscopes. Data transmission in optical fibres. Increasing brilliance in diamonds. 2 / 5 2) Which of the following is not an effect of refraction? 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. 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. light changing direction in an optical fibre is due to TIR. 3 / 5 3) A partial reflection is observed under which conditions? Only when light passes from an optical denser medium into an optically less dense medium. Only when light passes from an optical less dense medium into an optically denser medium. When light crosses a boundary between any two media of differing optical densities. From the surface of a plane mirror. 4 / 5 4) 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. 5 / 5 5) A student uses a ray box and a semicircular glass block, as shown below, to investigate refraction. She obtains the following results: Which set of results is likely to be incorrect? B A C D Your score is Restart quiz
