The refractive index of J is given by: (sin 23º)/(sin 47º) 23º/47º (sin 47º)/(sin 23º) 47º/23º 3 / 5 3) 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. 4 / 5 4) 2024 S4 EOY P1 Q09 A ray of monochromatic light in air is incident on transparent blocks of different shapes.
