In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
What are 5 examples of electromagnetic radiation?
- Radio Waves.
- TV waves.
- Radar waves.
- Heat (infrared radiation)
- Ultraviolet Light (This is what causes Sunburns)
- X-rays (Just like the kind you get at the doctor’s office)
- Short waves.
What are the 7 types of electromagnetic radiation?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What are three examples of electromagnetic radiation?
Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. (a) Longer wavelength; (b) shorter wavelength. Electromagnetic waves are produced by the motion of electrically charged particles.
What is the definition of electromagnetic radiation?
Radiation that has both electric and magnetic fields and travels in waves. … Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Also called EMR.
What electromagnetic wave is the most dangerous?
What are some examples of electromagnetic waves in your daily life?
Behaviour and uses of electromagnetic waves
- Radio waves. Radio waves are used for communication such as television and radio. …
- Microwaves. Microwaves are used for cooking food and for satellite communications. …
- Infrared. …
- Visible light. …
- Ultraviolet radiation.
How do you identify radiation type?
To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.
What are the 4 types of electromagnetic radiation?
The electromagnetic spectrum
- Gamma radiation.
- X-ray radiation.
- Ultraviolet radiation.
- Visible light.
- Infrared radiation.
- Microwave radiation.
- Radio waves.
What are the two types of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.
What can cause electromagnetic radiation?
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced.
What indicates that electromagnetic waves travel?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. … This proved that radio waves were a form of light!
What are the characteristics of electromagnetic radiation?
Properties of Electromagnetic Radiation
These magnetic and electric waves travel perpendicular to each other and have some characteristics like wavelength, amplitude, and frequency.
What is another word for electromagnetic radiation?
•radio wave (noun)
microwave, frequency wave.
What is another name for electromagnetic energy?
The energy in electromagnetic waves is sometimes called radiant energy.
What are the benefits of electromagnetic radiation?
The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi.
