Question

how can we see the objects

Answer 1

object reflects the light which help us to see them

Answer 2

When a beam of light falls on an object the object reflects the light in different directions ,our eye does'nt sense the the light directly , directly in the sense that they are not sensed by our eyes without being reflected from any obstruction.Our eyes sense the light rays which is being reflected from the objects.Hence, this is how we are able to see the objects and we can also conclude that light is an energy which we can't see or sense but it produces the sensation of vision in our eyes.
