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 three components of the electromagnetic spectrum?
- The electromagnetic spectrum includes common regimes such as ultraviolet, visible, microwave, and radio waves.
- Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I).
What are the 2 components of electromagnetic waves?
Electromagnetic waves have an electric (E) field component and a magnetic (H) field component that oscillate in phase and in directions perpendicular to each other.
What are the 7 components of the electromagnetic spectrum?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
What are the 4 main properties of electromagnetic waves?
Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.
What are the 7 types of waves?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
- Radio Waves: Instant Communication. …
- Microwaves: Data and Heat. …
- Infrared Waves: Invisible Heat. …
- Visible Light Rays. …
- Ultraviolet Waves: Energetic Light. …
- X-rays: Penetrating Radiation. …
- Gamma Rays: Nuclear Energy.
What are 4 types of waves?
Types of Waves – Mechanical, Electromagnetic, Matter Waves & Their Types.
What are the main components of radio waves?
Radio waves are radiated by charged particles when they are accelerated. They are produced artificially by time-varying electric currents, consisting of electrons flowing back and forth in a specially-shaped metal conductor called an antenna.
What are the types of waves?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
