تعريف ışın saçma في التركية الإنجليزية القاموس.

radiation

the spread of a group of organisms into new habitats

{i} energy radiated in the form of waves or particles; process of emitting energy in electromagnetic waves or moving particles; act of emitting, act of beaming or glowing

emission of energy in the form of waves or particles

a term with two broad meanings In the narrow sense, some type of electromagnetic wave: radio, microwave, light (infra-red, visible or ultra-violet), x-rays or gamma rays are all types of radiation Colloquially (the full term is "ionizing radiation") it means any spreading emission which can penetrate matter That includes x-rays and gamma rays, but also high-energy ions and electrons emitted by radioactive substances, accelerated by laboratory devices or encountered in space (e g the "radiation belt" and "cosmic radiation")

The emission and propagation of energy by means of electromagnetic waves or sub-atomic particles

The emission and propagation of energy by means of electromagnetic waves or particles (cf ionising radiation)

The process of radiating waves or particles

Energy in the form of electromagnetic waves or particles capable of damaging cells by removing electrons from atoms or molecules This damage can lead to cancer or other defects

Energy transmitted through space as waves or particles

Energy radiated in the form of waves or particles; photons

the act of spreading outward from a central source

The shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat

The emission and propagation of energy in the form of electromagnetic waves

Energy moving through space in the form of waves or particles Radiation can be ionizing, like alpha particles, beta particles, neutrons and X-rays, or non-ionizing, like visible light, heat, microwaves and radio waves Non-ionizing means that the energy level is too low to ionize the atoms

the process of heat transfer by means of infra-red radiatins, a form of electromagnetic wave Electromagnetic waves do not need any material medium for their propagation Space is almost completely empty, so the sun's heat cannot reach us by conduction or convection Because electromagnetic waves don't need a medium they are able to travel through space Anything above the temperature of absolute zero is able to emit and absorb infra-red radiations Radiation is absorbed by darker surfaces and reflected by lighter surfaces This is why people wearing darker clothing in the summer are hotter than thoose wearing white or light clothing Those wearing black will absorb the radiaions, therefore their temperature will rise

The process by which energy is propagated through any medium by virtue of the wave motion of that medium Electromagnetic radiation, which emits heat and light, is one form Sound waves are another

Energy propogating in the form of electromagnetic waves or photons

The emission or release of energy in the form of waves or rays

some type of electromagnetic wave: radio, microwave, light (infrared, visible or ultraviolet), x-rays or gamma rays are all types of radiation
