A fish appears bigger than its actual size to an observer above water. 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 ray of light changes direction as it travels through an optical fibre. light changing direction in an optical fibre is due to TIR. 2 / 5 2) 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 an anticlockwise direction. 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. 3 / 5 3) What is critical angle for glass (refractive index 1.50) at a glass-air boundary? 30º 45º 42º 90º 4 / 5 4) A ray moves from substance X into substance Y. What is the angle of refraction shown? 70º 30º 20º 40º 5 / 5 5) Which diagram shows light leaving an object under water and entering into an eye above the water. Your score is Restart quiz
