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.
Why do hairdressers have uv light?
The UV light causes DNA damage in bacteria, so it is used to sterilize the equipment.
What electromagnetic waves damage the human eye?
Answer #1:UV rays are damaging to the eyes, and if you are exposedfor too long can cause vision loss=========================Answer #2:Any radiation with wavelengths shorter than visible light can damage living tissue, including eyes. The shorter they are, the more dangerous.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
How do you get a UV light?

Why do UV tubes glow blue even though UV radiation is invisible to the human eye?
A UV tube gives off some blue light as well as UV radiation :)
Do you need to wear goggles when using UV light?

What adverse effect can result from overexposure of human tissues to uv light?
The excess exposure and ultraviolet light dosage can and will result in damage to human tissues. Two forms of damage include burns and inducing cancer causing mutations.
Will UV light cause damage to human cells?
Yes, UV light can be very damaging tot the skin. It is one of the primary causes of skin cancer as well as wrinkles and age spots.
Does UV light vibrate too quickly to see it?
UV light vibrates at a rate so fast that the naked eye cannot see it. Light energy's vibration is invisible to the naked eye, whether UV or not.
What type of wave is a UV light?
A UV light radiates energy in the form of electromagnetic waves with wavelengths shorter than those of violet light but longer than those of x-rays. The radiation is invisible to the human eye.
Can you grow marijuana with a uv bulbs?
No, marijuana needs red and blue spectrum lights to grow, it needs 6500K (color temperature) light for vegging and 2700K light for flowering. UV light will just damage the plant
Why do hairdressers have uv light?
The UV light causes DNA damage in bacteria, so it is used to sterilize the equipment.
What type of damage to human tissues can result from prolonged exposures to to UV radiation?
The excess exposure and ultraviolet light dosage can and will result in damage to human tissues. Two forms of damage include burns and inducing cancer causing mutations.
