light since you cannot see them
No, the human cannot see ultraviolet rays with the naked eye.
You cannot see air. Light passes through it.
Our eyes do not respond to heat waves, which is why we cannot see them. Light waves, on the other hand, are detected by our eyes and this makes us see.
If you can see the light reflected, then it has hit your eyes, and your brain is processing it as the sense of sight, if you cannot see it, then it has reflected somewhere other than your eyes-IE; back into space, or it is a wavelength of light that the human eye cannot detect.
We cannot see a light source even if 1 opaque material is blocking the light source. Opaque materials do not allow light to pass through them so we cannot see light through them but we can still see light reflected by them.
light since you cannot see them
because if we do not have light we cannot see
NO, HUMANS CAN SEE LIGHT BETWEEN THE WAVELENTHS OF VIOLET AND RED. HUMANS CANNOT SEE ULTRAVIOLET OR INFRARED LIGHT.
starfish have eyes but they can only see light and dark, but they cannot see clearly, so no, they cannot see in the dark.
Anything that is not living cannot see you but you can still see them by the reflection of light
It is rays of light
you can only see when its light and when its dark you cannot see
There are not different "forms" of light. There are, however, various wavelengths of light. A small portion of which we can see as "visible light," and most of which we cannot see directly with the human eye.
No, the human cannot see ultraviolet rays with the naked eye.
their eyes cannot see
Technically, you can't "see" a black hole, since no light can escape from it, therefore the light cannot reach your eyes.
