Ultraviolet light is invisible to the human eye. UV light is found in sunlight and is emitted by electric arcs and specialized lights such as black lights. It can cause chemical reactions, and causes many substances to glow or fluoresce. Most ultraviolet is classified as non-ionizing radiation.
The word "visible" has been given to a certain range of wavelengths/frequencies of
electromagnetic radiation, to indicate that it is the range within which the radiation,
when it enters the eyes of humans with normal vision, is consciously perceived. In
short, it is entirely accurate and proper to state that light which is categorized as
"visible" can indeed be seen by humans and, moreover, that that which is not cannot.
Be.
yes. ultraviolet can hurt humans by causing sun burns !
No, ultraviolet light is above the visible light spectrum.
The human eye does not see ultra-violet light by definition.
Humans don't see ultraviolet light, precisely because "ultraviolet" is defined as light beyond the visible range for humans.
No it is absorbed by the lens
infrared radiation is invisible to humans
Not to the unassisted eye.
YES. Visible light is the leading cause of death of humans on the Earth and is extremely dangerous. THIS IS IMPORTANT. If you see visible light in the wild, DO NOT APPROACH IT. I am the administrator of the Organization for Protection Of Humans from the Dangers of Visible Light (OPOHDOVL). Always remember to watch out for visible light in the daytime. That's when they get you!
"By virtue of the visible light cast by the headlights mounted on the front of my car, I was able to see and avoid the deer standing in the road, pausing only to make further use of the visible light and snap a photograph to capture the look of terror in the eyes of the hapless beast."
The only part of the electromagnetic spectrum that we can see is the small yet significant part of visible light. Visible light is not harmful for humans, but some of the other types of waves are.
in electromagnetic spectrum visible light is safe for humans
No. They're called the visible spectrum, the range of wavelengths us humans can see.
No, microwaves aren't visible to humans. Microwaves are electromagnetic energy, and the only electromagnetic energy humans can see is that of visible light.

To see things.
Only in the 'visible light' spectrum.
Visible light doesn't have to be invented. Light is a naturally occurring phenomenon under some circumstances, and the part that us humans can see we call "visible light".
Different wavelengths of visible light are different colors.
Humans are able to see light (hence called "visible light" on the electromagnetic spectrum). Otherwise, you couldn't see anything. (And I have a B in science class...PLEASE)

Visible light.
If your vision is normal, then you CAN see visible light.
The part that can be seen by human eyes is called visible light.
