Mar 31, 2023 · What you will learn from this video. Electromagnetic radiation is a type of wave that transfers energy. It includes radio waves, microwaves, infrared waves, visible light, UV light, X-rays, and gamma rays. The difference between all of these is the wavelength of the radiation.
- Water waves, sound waves, light waves, and waves in a string or slinky are examples of waves in everyday life.
- Vibrations in matter cause waves. (Students are likely to be familiar with vibrations causing sound waves and with disturbances in water causing wa...
- Waves can cause matter to move back and forth in place, but waves do not transport matter. Examples include sound causing matter to vibrate as the...
- Radiation refers to electromagnetic waves, which are one specific type of wave. Light refers to the portion of the electromagnetic spectrum that is...
- Aside from the type of wave (mechanical vs. electromagnetic), one wave can be distinguished from another by its measurable properties: energy, wave...
- Vision (visible light), communications/entertainment (radio waves), medical imaging (X-rays), cooking food (microwaves), heating (infrared), and su...
- All electromagnetic waves transfer energy. When this energy is absorbed by matter, it is converted into heat because it causes the particles in the...
- The main pattern observed in the electromagnetic spectrum is that waves with shorter wavelengths and higher frequencies have higher energy. For a w...
- Electromagnetic waves include radio waves, microwaves, infrared waves, visible light, ultraviolet light, X-rays, and gamma rays. All electromagneti...
- Students might have encountered radio waves (radio, TV, internet, cell phones), microwaves (microwave oven), infrared waves (heat from any object),...
Nuclear Radiation. Nuclear radiation comes from the nucleus, or center, of atoms. It is produced when the nucleus changes in some way. The nucleus of some types of atoms is unstable. An unstable nucleus can naturally change into another type of nucleus. When it does this, it shoots off nuclear radiation in the form of small particles or gamma rays.
Oct 16, 2023 · Both gamma rays and x-rays are photons with very high energies, and gamma have even more energy. They are also a type of ionizing radiation. Gamma rays can travel through thicker materials than x-rays can. Gamma rays are produced by some types of radioactive atoms. Cobalt-60 and potassium-40 are two isotopes that emit gamma rays. Cobalt-60 is ...
Apr 24, 2017 · NASA defines the spectrum as "the range of all EM radiation." EM stands for electromagnetic — a term that describes light you can see and radiation you can't. The science behind the light spectrum may not be simple, but it's still possible to teach kids how it affects everything from radio transmissions to microwaves. Advertisement.
NRAO/AUI. The warmth of the sun, an X ray taken in a doctor’s office, the sound of a guitar, and electricity generated in a nuclear power plant all have one thing in common. They are results of radiation. Radiation is the movement, or propagation, of energy from one place to another. From a human perspective, some radiation is directly useful ...
Light from the Sun provides energy for life on Earth. Plants change the energy of sunlight into food energy. When light rays strike a green plant, some of their energy is changed to chemical energy, which the plant uses to make food out of air and minerals. This process is called photosynthesis.

Gamma Rays: Gamma rays have the most energy of any wave in the electromagnetic spectrum and are produced by the hottest and most energetic objects in the universe. Earth's Radiation Budget : The energy entering, reflected, absorbed, and emitted by the Earth system are the components of the Earth's radiation budget.
