they are electromagnetic. So they have an electromagnetic spectrum.
Ultraviolet waves are smaller than light waves.
infrared light:)
Starting at ultraviolet, longer waves are waves of visible violet light, and shorter waves are X-rays.
Ultraviolet is higher frequency, then visible light, then infrared.
fluorescent
Ultraviolet (UV) light has a higher frequency (and a shorter wavelength and shorter period) than violet light. It is more energetic, too. We can't see UV light as our eyes only see up through violet. The shorter wavelengths of the UV light are something we cannot detect with our eyes. We can see (in order of increasing frequency) red, orange, yellow, green, blue and violet light. The UV light is outside the range of our vision.
Light waves that are of slightly higher frequency than you can see.
ultraviolet light
From the items on that list, infrared light has the lowest frequency, and X-rays have the highest.
Some insects use ultraviolet waves to find nectar. The ultraviolet light leaves marks on flowers, and the insects can sense them and find the nearby nectar.
You may experience sunburned skin if you allow your skin to be exposed to the ultraviolet waves that penetrate the clouds on a cloudy day. Ultraviolet waves are at the opposite end of the visible light spectrum from infrared waves. Ultraviolet (UV) waves are longer than X-rays.
Ultraviolet and visible light waves all travel at the same speed whenever they're all traveling through the same material.
