What is the speed of light in this material? 4.0 × 108 m s-1 1.5 × 108 m s-1 2.0 × 108 m s-1 3.0 × 108 m s-1 2 / 5 2) A partial reflection is observed under which conditions? Only when light passes from an optical denser medium into an optically less dense medium. When light crosses a boundary between any two media of differing optical densities. Only when light passes from an optical less dense medium into an optically denser medium. From the surface of a plane mirror. 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 in an anticlockwise direction. 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 towards the normal. 4 / 5 4) In which digram is the path of light not correct? 5 / 5 5) A ray of light travels into a triangular prism and refracts into many colours. The colours at the two ends of the spectrum are red and violet. Which colour of light has the higher refractive index in glass, and why? Violet as violet light has a higher refractive index in glass, and thus bends more. Red as red light has a higher refractive index in glass, and thus bends more. Violet as violet light has a higher refractive index in glass, and thus bends less. Red as red light has a higher refractive index in glass, and thus bends less. Your score is Restart quiz
