Light is a form of electromagnetic radiation that is visible to humans. Usually when someone talks about "radiation" they are thinking of the hard gamma wavelength radiation that is emitted by nuclear reactors, some radioactive isotopes, and nuclear explosives.
In a scientific sense, radiation means any emission on the electromagnetic spectrum and ranges from the very long wave-length, low-frequency, low-power radio wave up through microwaves (the same stuff you cook food with), infrared (aka heat), visible light, ultraviolet light, x-rays, and finally the very short wave-length, high-frequency, high power gamma rays.
There are many more types of radiation than I've listed here, but all are essentially a mass-less particle called a photon, moving in a wave shaped pattern. The only difference between types of radiation is the wavelength and amount of energy the photons contain.
Gamma rays are a form of electromagnetic radiation, just as light is, and all EM waves propagate at the speed of light through a vacuum.
No. Nothing can travel faster than light.
No, both light in air and radiation from a microwave oven travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Therefore, they both travel at the same speed.
Cherenkov radiation. It is produced when a charged particle, such as an electron, moves through a medium at a speed greater than the speed of light in that medium. The result is a characteristic blue glow.
No. Heat is infrared radiation ("infra" means "lower"). Lower frequency means longer wavelength. All radiation is captured by antennas that resonate at the frequency of the radiation. The "antennas" for visible light are electrons that use the radiation to jump into excited states and cause optical neurons to fire. The "antennas" of heat (infrared) are bigger -- they are molecules that jiggle faster when the radiation hits them. That jiggling is heat.
no
The speed of electromagnetic radiation of all kinds, including light, is faster than the speed of anything else.
radiation radiation travels at the speed of light, which is very quick diffusion is slow. convention is faster than diffusion.
Please note that it is NOT POSSIBLE to go faster than the speed of light in a vaccum. It probably never will be possible. However, since you didn't specify "vacuum", the answer is basically "yes" - and this has actually been observed. A particle that goes faster than the speed of light in the medium in which it is travelling will slow down, and in doing so, it will emit Cherenkov radiation. For more details, see the Wikipedia article on Cherenkov radiation.
No plane is faster than light.
No material object can exceed the maximum speed of light, 299,792 km/second in a vacuum. However, energetic electrons can reach extraordinarily high speeds, and in water can go faster than (and overtake) light radiation, which is slowed to around 224,910 km/second.It is theoretically possible, however, that one could somehow change reference planes and cross a distance faster than the light does that remains in that reference plane. This would not be going faster than light, but merely taking a shortcut.
Nothing has been proven, however ! while scientist at the CERN collider may be on the verge of disproving light is the fastest thing. there are some happenings that totally suggest that light is not the fastest thing. if a black hole being one that is a dark planet due to the fact that all light is bent by gravity so it appears black raises the simple questions. if light was faster than gravity! it would escape the planet feald if it was. so gravity is faster if light as it would escape. then the second dilemma is that a black hole can be found by the radiation that they emit so this raises two fold question that is if radiation escapes then it is faster than gravity so making it faster than light. however many will say no, simply because it has never been proven and on other foundation they do say it is not so. Bering in mind no person knows the speed of gravity nor the speed of radiation or gamma rays so, these are all up for potentially being faster than the speed of light.
Radiation is the form of heat transfer affected by color. Dark colors absorb more thermal radiation than light colors, so they heat up faster when exposed to sunlight. Light colors reflect more radiation, resulting in lower heat absorption.
Gamma rays are a form of electromagnetic radiation, just as light is, and all EM waves propagate at the speed of light through a vacuum.
the thing which is faster than light is neutrinos which is 25parts per million faster than speed of the light, its scientifically proved.
No. Nothing can travel faster than light.
UV radiation carries more energy because it vibrates faster, i.e. it has a shorter wavelength. Because it carries more energy, it can do much more damage than visible light.
