Light is invisible until it hits an object. It can only be visible to us whenever it get scattered or bounced off the dust particles in the intervening medium. We can see the source of light like stars at night as they are too dim to light up much but that light does hit our eyes and therefore we see the light. The above discussion on visibility of light is only confined to the electromagnetic radiation of wavelength from 400 nm to 700 nm which is called visible light, as these electromagnetic radiations gives the sensation of sight.
Light is, perhaps, the most wonderful of all visible things.
