Is it possible to see UV light?

According to almost any source about the light spectrum, visible light, the portion of the electromagnetic spectrum that is visible to the human eye, is the range of wavelengths between 400 to 700 nanometers. Ultraviolet light (UV), which ranges from 10 to 400 nanometers, is not detectable to the human eye.2018-08-21

What would it look like if we could see infrared light?

Infrared. If you could see infrared light, you would see a world of temperature—not color. Any object that has a temperature radiates in the infrared part of the spectrum (even ice). The hottest objects would appear brightest, so the sun will still be at the top of the list.

Is UV light just purple light?

What is this? UV or ultraviolet light has a shorter wavelength than the light that’s visible to us, meaning that we’re simply not able to see it. The name comes from the fact that it is right below our visible spectrum, below the first light color that we can see, and that’s violet.2019-08-14

UV light has a shorter wavelength than visible light. Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of “purpler-than-purple” light or “beyond violet” light.

Is UV light just blue?

At the other end of the visible spectrum, past the visible blue light, is a light wave that’s too short for us to see. We call these waves blue-violet, or ultraviolet (UV) radiation. Since UV rays have higher energy than visible light rays, high exposure to them can cause suntans, sunburns, and eye damage.
