Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.Dec 7, 2015

What is radiation in physics and examples?

Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.

What is radiation short definition?

(RAY-dee-AY-shun) Energy released in the form of particle or electromagnetic waves. Common sources of radiation include radon gas, cosmic rays from outer space, medical x-rays, and energy given off by a radioisotope (unstable form of a chemical element that releases radiation as it breaks down and becomes more stable).

What is radiation examples?

Radiation Examples heat from a stove burner. visible light from a candle. x-rays from an x-ray machine. alpha particles emitted from the radioactive decay of uranium. sound waves from your stereo.

How do you explain radiation to a child?

Radiation is energy that moves from one place to another. Light, sound, heat, and X-rays are examples of radiation.

Is radiation and wave same?

Water waves transmit energy through space by the periodic oscillation of matter (the water). In contrast, energy that is transmitted, or radiated, through space in the form of periodic oscillations of electric and magnetic fields is known as electromagnetic radiation.

What does the word radiation mean when used by scientists quizlet?

Radiation: Information from Space and Light. – Light behaves both as a wave and a particle. – Light can travel through empty space. Unlike light, sound waves need a medium to propagate. – Light is composed of electric and magnetic waves electromagnetic radiation.

Is there radiation in everyday life?

Radioactivity is a part of our earth – it has existed all along. Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink.

Does radiation stay in your body forever?

The radiation stays in the body for anywhere from a few minutes to a few days. Most people receive radiation therapy for just a few minutes. Sometimes, people receive internal radiation therapy for more time. If so, they stay in a private room to limit other people's exposure to the radiation.

What are 5 examples of radiation?

Examples of Everyday Radiation

• Visible light.
• Infrared light.
• Microwaves.
• Low-frequency waves.
