An optical medium which has different composition at different points - Heterogenous An optical medium which has different composition at different points is called heterogeneous medium. A body which does not allow light to pass through it - opaque Those bodies which do not allow the light energy to pass through them are called opaque bodies. The speed of light - 3×10 8 m/s The speed of light is the distance light can travel in a unit of time through a given substance. The path along which light energy travels in a given direction - Ray of light The path along which light energy travels in a given direction is called a ray of light. A body emitting light on its own - Luminous All bodies which emit light energy by themselves are called luminous bodies. Column A Column B 1 .
