Does UV radiation have more energy than violet light?
Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
What is elctromagnetic energy?
Energy that is radiated in a wave such as radio waves, white light, uv light and xray.
What are two light energy waves that you can't see?
The two ligh energy waves that you can't see are ultra-violet (UV), and infra-red (IR). Ultra-violet light waves are measured at 380nm and below, infra-red light waves are 750nm and above. Normal light that you can see resides between these two regions.
Which type of energy gives us sunburn?
Electromagnetic energy waves on the UV light spectrum.Ultraviolet.UVB
Does UV radiation have more energy than violet light?

How is ultraviolet light more damaging to cells than infrared light would be?
UV is higher energy than IR and can therefor deposit more energy in cells.
Basic principle of uv?
The basic principle is that UV light is high energy light with shorter wavelength.
Why are there no substances that convert visible light into UV?
UV has higher energy (per photon) than visible light.
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
Does ultraviolet light carry more energy than infrared radiation?
Yes. Radiations on the "red" end of the spectrum, such as radio, microwave, and infrared, have markedly less energy than visible light. Frequencies on the "purple" end, on the other hand, such as ultraviolet, x-ray, and gamma, have considerably more.
Visible light fits between x-rays and uv?
No, the visible light region is between Infra-red and UV.
What is elctromagnetic energy?
Energy that is radiated in a wave such as radio waves, white light, uv light and xray.
Which form of electromagnetic radiation has more energy than visible light waves have?
Ultraviolet (UV) radiation has more energy than visible light waves.
Why red colour reflect only red light?
No, red glass does not only reflect and transmit red light waves. It actually transmits the white light waves through the red glass creating a red glow. A transparent object generally transmits light while a solid object reflects light.
Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
What is the difference between high engery light like UV and low energy light like red light?
The frequency of Ultra violet is about twice as high as infrared light. 400 nanometers to 800 nanometers. The quantum side says they are packets of energy and blue packs a bigger wallop than red.
