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 characteristics of electromagnetic waves?
Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum.
All electromagnetic waves:
- are transverse waves;
- can travel through a vacuum ;
- travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.
What are the different regions of the electromagnetic spectrum What do all electromagnetic waves have in common How do they differ?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
What are four characteristics of electromagnetic radiation?
- 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.
- (iv) They travel through vacuum with same speed,
Which of the following regions of the electromagnetic spectrum has the greatest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
Which of the following regions of the electromagnetic spectrum has the shortest wavelength?
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
How are the different parts of the electromagnetic spectrum arranged accordingly?
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. … The spectrum of waves is divided into sections based on wavelength.
Which of the following regions of the electromagnetic spectrum has the lowest energy?
Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.
Which two regions of the spectrum have the greatest ability to bend?
6. It is known that electromagnetic waves with longer wavelengths have a greater ability to bend around obstacles that get in their path.
Which part of the electromagnetic spectrum has the lowest frequency?
The electromagnetic spectrum
Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.
