Answer:
light is a from of energy which enables us to see things around us. light travels in a straight line(rectilional propogation)
Our eyes alone cannot see any object. it is possible only when light reflect from an object's entered our eyes.
The light by which we can see an object may have been emitted by the object (if the object is luminous)or may have been reflected by the object (if the object is non luminous)
