No, UV rays are a kind of electromagnetic radiation - a kind of light. They have a wavelength shorter than the violet light visible at the edge of a rainbow and hence can't be seen with our eyes.
Alpha radiation, on the other hand, is a kind of matter radiation. As the large, unstable nuclei of certain elements breaks down, it can eject little clumps of protons and neutrons (2 of each - equivalent to a helium nucleus) and it is these little clumps of ejected matter that form alpha radiation.
The word radiation is a little confusing, since people often think that radiation is a thing in itself. In fact, radiation is a description of how things are emitted. Think of a transparent sphere with a light-bulb in the centre and you can imagine the rays of light coming directly out from the centre in straight lines, exactly like the radius of the sphere. Likewise with a little piece of uranium (a radioactive metal element) the little ejected particles will come flying out in straight lines from the centre like the radius of the sphere. It is because each of these is like the RADIus that it is called RADIation.
What else can I help you with?
Are UV light and UV rays the same thing?
Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.
What type of radiation ionises substances?
Ionizing radiation includes alpha, beta, and gamma rays, X-rays, and some UV rays. These types of radiation have enough energy to remove tightly bound electrons from atoms, creating ions.
What are 5 different types of radiation and which are the most dangerous?
Five types of radiation include alpha, beta, gamma, neutron, and electromagnetic radiation (such as x-rays and UV rays). Gamma and neutron radiation are generally considered the most dangerous due to their ability to penetrate deep into tissues and cause severe damage.
Does UV rays have longer wavelength than infrared?
No, UV rays have shorter wavelengths than infrared rays. UV radiation has shorter wavelengths and higher energy levels compared to infrared radiation.
Can you tan with UV 6 rays?
UV 6 rays do not exist. Tanning is typically achieved with UVB and UVA rays from the sun or tanning beds. UV 6 rays are not a recognized form of ultraviolet radiation.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.
What type of radiation ionises substances?
Ionizing radiation includes alpha, beta, and gamma rays, X-rays, and some UV rays. These types of radiation have enough energy to remove tightly bound electrons from atoms, creating ions.
What radiation is not used for communication?
Gamma rays, x-rays, UV radiation and so on.
What is the name of energy from the sun?
Solar Radiation, or UV rays. UV stands for Ultraviolet rays.
How does ozone protect us from ultraviolet radiation?
Ozone blocks the UV rays. UV rays are harmful rays of the sun.
What does the atmosphere do to some of the radiation?
It absorbs some of the radiation. The radiation is UV rays.
How do you spell uv rays?
The acronym UV rays stands for ultraviolet radiation, a level of electromagnetic radiation that has a shorter wavelength than visible light.
What are 5 different types of radiation and which are the most dangerous?
Five types of radiation include alpha, beta, gamma, neutron, and electromagnetic radiation (such as x-rays and UV rays). Gamma and neutron radiation are generally considered the most dangerous due to their ability to penetrate deep into tissues and cause severe damage.
Is the UV radiation the sortest wavelength?
No, gamma rays have the shortest wavelength.
Does UV rays have longer wavelength than infrared?
No, UV rays have shorter wavelengths than infrared rays. UV radiation has shorter wavelengths and higher energy levels compared to infrared radiation.
Which gas filters out the UV rays from the solar radiation?
Ozone filters out the UV rays. It is present as ozone layer.
How are phytoplankton affected by UV radiation?
Ozone depletion allows the UV rays to come in. These rays kill the planktons.
