Light rays when travellingfrom Benzeneto Air bends …………………. .

Answer»

Solution :LIGHT rays when travelling OBLIQUELY from Benzene to Air, bend `ul("away from the normal")`.
Generally, when light rays travel obliquely from DENSER MEDIUM to RARER medium, it bends away from the normal as the velocity increase after entering air.
Benzene is a denser medium, while air is the rarer medium. Velocity of light in benzene is less than that in air.
