UV rays are electromagnetic waves have shorter wavelength than that of visible light(10nm to 400nm)
It can cause chemical changes, hence causes many substance to glow
It is non ionizing radiation
It can cause damage to living beings(harmful to humans) and is blocked by ozone layer
It may leads to cancer
It produces heat in surface of earth
Used to prevent counterfeiting
UV rays are used for wireless communication also
NO. By tradition and usage : current flows from positive to negative. In reality : electrons flow from negative to positive.
The ultraviolet light of the sun will give you good color, but too much exposure can be dangerous.
short wavelength
It takes 5 minutes.
yes, it will. But, the ozone layer will pretect us fron ultaviolet rays. PS. Ultraviolet rays come from the Sun!!
negative
Solar UV light is a type of ultraviolet (UV) radiation emitted by the sun. It is divided into three wavelength ranges: UVA, UVB, and UVC. UV light can have both positive and negative effects on human health, as it can cause sunburn and skin cancer, but also helps the body produce vitamin D.
Maybe. We don't know, because there's no such thing as negative light.
A photograph turns black in light negative. In a photographic negative, the areas that receive more light appear black when the negative is converted to a positive image.
Dark blue is positive and light blue negative on right side and brown positive and yellow negative on the left.
No. They can not see in ultraviolet light. They are known to glow when exposed to ultraviolet light, though.
radiation, ultraviolet light, and the use of drugs
Ultraviolet light. That's why it's called so.
Ozone is the gas in the atmosphere that protects living things from ultraviolet light. It absorbs and filters out the harmful UV rays, preventing them from reaching the Earth's surface in large amounts.
Light has a longer wavelength than ultraviolet. Ultraviolet light has shorter wavelengths and higher energy compared to visible light.
ultraviolet light.
as i know its destroyed by ultraviolet light
