because it comes in ultraviolet region which our eyes cannot see..
Human eyes are not sensible to these radiations.
by observing in high-energy wavelengths such as X rays and long wavelengths of light such as radio waves
We have NO TROUBLE at all seeing visible light wavelengths from the sun.We cannot see the radio, microwave, infrared, ultraviolet, or x-ray "light" from the sun because our eyes are not sensitive to these wavelengths.
There are only certain wavelengths that can be accepted and absorbed by chlorophyll molecules. The rest are instead reflected - the colors that you can see. Without those wavelengths, you do not have photosynthesis.
It will be right to say that only principles of light microscopy keeps light focused and scatters wavelengths of visible light for the human eye to see.
Human eyes are not sensible to these radiations.
Approx. 350 nm.
We see wavelengths that are reflected off of matter.

You can see two photos of plutonium objects at the link below.
Different wavelengths of visible light are different colors.
Crocodiles can see at almost a 180 degree angle but cant see anything below there nose.
you cant get them from a shop you can get them on the internet see the related links below.
