Dear expects,WE CAN ABLE TO SEE THINGS BECAUSE OF LIGHT BUT,,,WHY WE COULD NOT ABLE TO SEE THE LIGHT??.
Dear Student,
We can only see reflected light. It means that when photons present in a beam of light bounces off an object, these reflected photons fall on our eyes and our retina recognizes them as images.
But why can't we see the light itself?
It is because light has photons traveling in a straight line and to see these photos, other photons must collide against them or these photons must themselves emit new photons. But this is not possible a photons do not emit photons. So, we are unable to see light.
Although, when there is dust in the air, the photons collide with these dudt particles and thus wee are able to see the trajectory of a light beam.
As there is no atmosphere and air on the moon, we have a black sky there as light does not reflect against anything.
Regards
