Question

Can we see light .light is visible to us or not????

Solution

Not exactly. We see things because they reflect light back into our eyes. So the absorption of light by the eye enables us to see. If there were no light, we wouldn’t see the things out there. If we were blind our eyes would be unable to absorb and process the reflected light so we wouldn’t see.

But when people say “seeing” they mean seeing something that’s out there. So I don’t think you can call light visible.

Maybe a better way to clarify this is to talk about hearing: We hear music and voices because they move the air, and the air changes density and becomes thicker and then thinner, and these density changes reach our ears and push the membranes in our ears. But still we talk about hearing the music - not hearing the air.

These days it’s very common in rock concerts, dance and theater, to fill the air with smoke so we can see the beams of light from all the computerized lighting instruments. But actually we’re not seeing the light itself - we’re seeing the illuminated smoke.

In short - light itself is not visible, but it allows us to see because our eyes are sensitive to light and our brains process the light signals that went into our eyes. So light hits an object and is reflected back into our eyes, and that allows us to see the object.
