UV radiation is given off by the sun. UV radiation is a broad spectrum that consists of UVA, UVB and UVC radiation. The planets atmosphere protects us from harmful UVA and 90% UVB radiation, leaving unharmful UVC radiation to pass through the atmosphere. However, due to the increasing number of greenhouse gases, Ozone is being broken down a lot faster than it should, which in turn means that more harmful UV radiation can come through, which means that we are at a higher risk of cancer.
What else can I help you with?
What causes uv rays?
Ultra-violet radiation from the sun is caused by the high temperature of the sun, which in turn is the result of nuclear fusion. High temperatures cause sub-atomic particles to vibrate rapidly, and vibrating electrons give off electromagnetic radiation. The faster the electrons vibrate, the higher the frequency, and the higher the energy content of the radiation that they radiate.
What is the colour of the fumes given off when crystals of iodine are heated?
The fumes given off when crystals of iodine are heated are purple in color.
What is a fast moving electron that is given off as a nuclear radiation?
Beta radioactivity radiation.
Heat given off by a fireplace is an example of?
radiation.
Heat given off by a fireplace is an example of what?
Radiation
When the nuclei break apart what is given off?
radiation
Heat given off by a fire in a fireplace is a example of?
radiation
What does radiation given off by radioactive waste not do?
Corrode metals
Which form of radiation given off by the earth causes heating of the earth's atmosphere?
Infrared radiation is the form of radiation given off by the Earth that causes heating of the Earth's atmosphere. This radiation is absorbed by greenhouse gases in the atmosphere, which traps heat and warms the planet.
What is emitted from the sun?
The sun emits a wide range of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation. These emissions are the result of nuclear fusion reactions occurring in the sun's core.
Heat given off by a fire in a fireplace is an example of?
C. Radiation
What is A fast moving electron that is given off as nuclear radiation?
Beta
