Why is there radiation in galaxies?
This is a difficult question to answer, like many things in science. We know they exist, but we wonder why. Gravity exists, we roughly know how it works and its effects, why it exists? It just does. It happened to be a part of the laws of physics put into motion once the universe formed. Radiation as it is commonly thought of, for example alpha radiation, is given off by the decay of certain elements. Radon gas is radioactive, thus it decays slowly to a more stable state and in doing so it releases charged particles - alpha. We know things happen, we know how they happen and can predict when. What we really will never know (probably) is why.
What effect the amount of electromagnetic radiation given by a fire?
i don't know
What is similar to heat radiation?
We know that infrared radiation can transfer thermal energy (heat) from one place to another.
What is made up of short invisible wavelengths of electromagnetic radiation?
We know that ultraviolet electromagnetic radiation is light that is higher in frequency than the light in the visible spectrum. It may be possible to argue that other shorter wave radiation could also be included, but the question has the feel of one that might be asked by an investigator who is beginning an inspection of the electromagnetic (EM) spectrum. Let's keep it simple and begin at the beginning, shall we?
What is the relative atomic mass of gamma radiation?
don't know
Does cubic zirconia emit radiation?
Cubic zirconia itself does not emit radiation. However, some cubic zirconia may have been treated with radiation or other processes to enhance its color, so it's important to know the origins of the specific stone you have to ensure it is safe.
How do scientists know black holes exist if these objects don't emit visible light?
They don't directly emit light, but anything falling into them will emit strong electromagnetic radiation - due to the acceleration of the matter falling into the black hole. Also, the black hole attracts all matter near it.
Do ice cubes emit infrared radiation?
No, ice emits thermal radiation. It just emits less than so called room temperature. You need to get down to absolute zero, around -273C, to stop the emission of thermal radiation, which is caused by thermal activity.
What are the 3 types of radiation with short wavelength and high frequency?
The three types of radiation with short wavelength and high frequency are X-rays, gamma rays, and ultraviolet (UV) radiation. These forms of radiation have energetic photons and can have harmful effects on living organisms if exposure is not controlled.
What are two kinds of radiation given out by torch bulbs?
Torch bulbs emit both visible light and infrared radiation. The visible light is what allows us to see the light produced by the bulb, while the infrared radiation is a form of heat energy that is also given off.
All objects emit and absorb radiant energy?
Theoretically false. An object at the temp of absolute zero would emit no energy or radiation. However, absolute zero does not exist in nature (as far as we know), therefor, in a practical sense the statement is true.
What determines the radiation that an electromagnetic wave emits?
You're probably thinking of frequency and wavelength. If that's true, then you onlyneed one or the other. They're tightly connected, so if you know one of them, thenyou can always calculate the other one.
Why can both the sun and earth be treated as blackbodies?
Both the sun and earth can be treated as blackbodies because they absorb and emit radiation at all wavelengths. A blackbody is an idealized object that absorbs all incoming radiation and emits radiation based on its temperature, which is true for both the sun and earth to a certain extent.
Is there a site where you can have your short story reviewed before you hand it in to your teacher?
Not that I know of, get your mother, father or carer to look at it.
Is infrared radiation only emitted from the center of hot solid objects?
No. While most infrared radiation is from the center of hot solid objects, some of it is not. The sun is plasma (not solid) and it emits infrared radiation. Also, infrared radiation can be emitted by the friction in between objects
Short note on light?
"Light" is a very narrow band of radiation in the electromagnetic spectrum - approximately 400 nanometers (nm) to 700 nm. It is located between ultraviolet and infrared radiation and is special because we have evolved the capability to see this radiation as the light that we know and all of its colors.
How do you know if something is radioactive?
You can detect radioactivity using a Geiger counter or other radiation detectors. Radioactive materials emit ionizing radiation such as alpha, beta, or gamma particles, which can be measured to determine the level of radioactivity. Additionally, certain properties like half-life and decay products can also indicate if a substance is radioactive.
