What are 5 properties of electromagnetic waves?
What are 5 properties of electromagnetic waves?
1 Answer
- They are transverse in nature.
- They consist of oscillating electric (E) and magnetic (B) field vectors at right angles to each other and at right angles to the direction of propagation of the wave.
- They can travel through a vacuum.
- They travel at the speed of light in vaccuum, c=3×108m/s.
How do you explain electromagnetic waves to a child?
Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency.
What are the uses of the electromagnetic spectrum?
Uses of Electromagnetic Waves
- Radio waves – radio and television.
- Microwaves – satellite communications and cooking food.
- Infrared – Electrical heaters, cooking food and infrared cameras.
- Visible light – Fibre optic communications.
- Ultraviolet – Energy efficient lamps, sun tanning.
- X-rays – Medical imaging and treatments.
What are the two properties of electromagnetic waves?
Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
What are electromagnetic waves and their characteristics?
Characteristic of electromagnetic waves are as follows: – (i) They do not require any material medium for their propagation. (ii) The oscillations of and are perpendicular to each other and are in same phase. (iii) They are transverse in nature.
What two properties do all electromagnetic waves possess?
What is an interesting fact about electromagnetic spectrum?
The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum.
Is there an upper limit to the electromagnetic spectrum?
There are no upper or lower limits in the electromagnetic spectrum. At the long wavelength, low frequency end are radio waves. They have wavelengths of the order of 100 meters. Their frequency can be calculated because, c = λν.
What are the three regions of the electromagnetic spectrum?
The infrared portion of the electromagnetic spectrum is usually divided into three regions; the near-, mid- and far- infrared, named for their relation to the visible spectrum.
What is the Order of the electromagnetic spectrum?
The electromagnetic spectrum encompasses all types of electromagnetic radiation. From longest wavelength/lowest energy to shortest wavelength/highest energy, the order of the spectrum is radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray.
What can I See on the electromagnetic spectrum?
The electromagnetic spectrum range of radiation frequencies includes visible light such as that from a lamp in your house, those created by the microwave in your kitchen, and the frequencies that come from a radio station. As more applications use this spectrum to communicate, some bandwidths grow increasingly crowded.
