Radiation is photon or light. We give name for radiation by its' range of wavelength. Those with wavelength < 0.001 nm is called gamma ray, those below gamma to just about 0.1 nm is x-ray and those below x-ray are UV and visible light. Our visible light is light with wavelength 400-700 nm below that are infrered, microwave and radiowave.
What else can I help you with?
Is actinium a very powerful source of alpha radiation?
Yes, the isotope 227Ac emit alpha and beta radiations; all the isotopes of actinium are radioactive and emit radiations.
What does the ozone hole allow to reach Earth's surface?
The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.
How does the ozone protects life on earth by absorbing certain wavelengths of what?
The ozone protects life on earth by absorbing certain wavelengths of ultraviolet radiations. These radiations are high frequency radiations which can cause serious harm to living organisms.
What type of radiations give electricity?
Since any radiation contains energy, it follows that most radiations can be converted into electricity, with the appropriate equipment.
How is ozen layer protecting the earth from ultra violet rays?
Ozone layer is present in the stratosphere region of the atmosphere. It protects us from the harmful ultraviolet radiations of the earth. It block the radiations which are harmful while allows the useful radiations to pass through.
What does uranium emits while it breaks down?
Fission fragments, neutrons, gamma radiations; and all the radiations emitted by these fission fragments.
Is actinium a very powerful source of alpha radiation?
Yes, the isotope 227Ac emit alpha and beta radiations; all the isotopes of actinium are radioactive and emit radiations.
What is the differences between visible and invible radiation?
Radiations within the range of 200 - 400nm are Visible Radiations. And others out of this range are invisible radiations.
Why are all of the places along the equator hot?
This is due to the Near Proximity to, and of, Solar Radiations.
When is the sun at maximum UV strength?
All the UV rays originate from the sun. It is the source of all UV radiations.
Whiat layer of the earths atmosphere protects us from harmful radiations?
Ozone layer protects us from harmful radiations. UV radiations are these rays.
Why the sea is blue?
From the spectrum of the visible light water absorb red, orange, yellow and green radiations. And the result is that we see the blue and violet radiations. Red, orange, yellow and green radiations have longer wavelengths than blue, indigo and violet radiations. The depth of water and variation of composition play also a role.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
What has radiations has the smallest wavelength?
Gamma rays have the smallest wavelength among all types of radiation.
What does the ozone hole allow to reach Earth's surface?
The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.
Are all the radiations are electro magnetic radiations?
No, not all radiation is electromagnetic radiation, though some is. Exceptions: Neutron radiation - Emission of neutrons. Alpha decay - Emission of a helium-4 nucleus (2 protons and 2 neutrons). Beta radiation - Emission of electrons.
What is it when something absorbs ultraviolet radiation?
Ozone absorbs UV radiations. They are high radiations rays.
