Electromagnetic Radiation. Energy that is propagated through space-time with magnetic and electrical fields running perpendicular to each other and perpendicular to the flow of energy.
What is the meaning 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 is electromagnetic energy quizlet?
electromagnetic energy is defined as. A form of energy that travels through space as waves. What are radio waves. Electromagnetic waves with the longest wavelengths and lowest frequencies.
Which of the following is a type of electromagnetic radiation?
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 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 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.

What are the 4 types of electromagnetic radiation?
The electromagnetic spectrum
- Gamma radiation.
- X-ray radiation.
- Ultraviolet radiation.
- Visible light.
- Infrared radiation.
- Microwave radiation.

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 electromagnetic radiation is harmful?
There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic spectrum and can damage DNA or cells directly.
