What is the difference Radiation and irradiation?
Radiation is emitted from something and travels from its point of origin to somewhere else. When radiation hits something else (and is therefore stopped) the thing that has been hit is said to have been irradiated. Thus a sunbather is undergoing irradiation by radiation emitted by the sun.
Are alpha beta or gamma emitted by the sun?
Yes, all three forms of radiation are present in the sun. Alpha particles are simply helium atoms, and helium is being formed constantly by the fusion of hydrogen, although this is not considered alpha radiation as it is not involving radioactive decay. Beta radiation is high energy electrons, which are likely to be present in the sun. And finally, gamma rays are emitted during the process of fusion. However, the vast majority are absorbed within the Sun's core and therefore do no radiate from the Sun.
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
The energy from the Sun arrives through the process of radiation what forms of energy can be transferred through radiation?
radiant energy
Why can radiation travel in a vacuum?
yes as radiation travels from the sun through a vacuum to earth
Definition of solar radiation?
The types of radiation that are emitted from the Sun.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
In fact, radiations are reflected by earth but not emitted.
How long are the wavelengths of radiation emitted by Earth are?
Longer than those emitted by the Sun
What best describes the primary wavelength of radiation emitted by Earth's surface?
they are longer than those emitted by the sun.
The wavelengths of radiation emitted by Earth are?
they are longer than those emitted by the sun.
Is speed of radiation emitted by the earth faster than the sun's?
both are the same = c
What is a form of oxygen that protects us from high-energy radiation emitted by the sun?
Ozone
What types of energy are radiated from the sun?
All "energy wavers" are forms of radiation. Most of the spectrum is emitted from the sun in varying amounts from xray, all the way down to radio waves. Visible light is a form of radiation, one which most directly affects us.

What is emitted from the sun?
The sun radiates ultra-violet and visible light.
How does the energy produced in the sun reach the surface?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
What is a radiation injury?
Radiation injuries are caused by ionizing radiation emitted by sources such as the sun, x-ray and other diagnostic machines, tanning beds, and radioactive elements
