The blue light has longer wavelength, lower frequency, and
less energy per photon than the ultraviolet light has.
The blue light is also visible to the human eyes, whereas the
ultraviolet light is not.

Is ultraviolet a type of light?
Yes, Ultraviolet is a blue/purple type of light that is florescent.
Why are bug zappers light blue?
According to the website below, they are blue because blue is the closest wavelength of the visible spectrum to ultraviolet light, and insects are attracted to ultraviolet light.
Does ultraviolet light heat Earth's atmosphere the most or is it blue light?
It can cause sunburn, so it is yes for both answers. Light at the end of the spectrum,blue but invisible
How do the frequencies of blue light or red light compare?
The frequency of blue light is roughly double the frequency of red light.
What ems wave is necessary for photosynthesis?
Ultraviolet It need visible light. Red and blue light are more preferred.
Which of these kinds of electromagnetic waves has the lowest frequency x-rays infrared light ultraviolet light blue light or yellow light?
infrared light:)
Can scorpions see in ultraviolet light?
No. They can not see in ultraviolet light. They are known to glow when exposed to ultraviolet light, though.
What does an ultraviolet telescope collect?
Ultraviolet light. That's why it's called so.
Why does ultraviolet light appear blue?
Because its at the blue end of the light spectrum, visual light is in the middle (what we can see) and infra red is at the other (red end) of the spectrum. Does it appear blue? To whom? Or to what? Is ultraviolet and infrared light part of the visible spectrum? If not, then we don't know what they appear to be. A UV light source appears blue because the light waves it produces go down into the blue/indigo/violet frequency range. You can't see the ultraviolet light itself, just this "waste" light. There are two reasons they don't tune UV sources to just generate UV--it would be really expensive to build a bulb like that, and they want you to see the bulb's on so you won't look at it and harm your eyes.
An example of a carcinogen would be ultraviolet light or benzene?
ultraviolet light.
Riboflavin is destroyed by?
as i know its destroyed by ultraviolet light
Why is the blue star hotter?
When a star is blue it means it is putting out light mostly in the ultraviolet spectrum which is of a higher energy than infared light, or light in the visible spectrum. This means the star has more energy and heat.
