Best answer: What are the types of electromagnetic spectrum?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

What is the 7 electromagnetic spectrum?

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 type of spectrum is the electromagnetic spectrum?

The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

What are 3 uses for 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.

What is the best electromagnetic spectrum?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

What are 4 types of waves?

Types of Waves – Mechanical, Electromagnetic, Matter Waves & Their Types.

What is the highest frequency color?

When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.

What is the EM spectrum made of?

The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum.

What is the EM electromagnetic spectrum?

The electromagnetic spectrum, or EM spectrum, is the name given to the collection of all electromagnetic radiation in the universe. This is a type of energy that pervades the cosmos in the form of electric and magnetic waves, allowing for the transfer of energy and information.

What type of wave is an electromagnetic wave transverse or longitudinal?

Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave.

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 characteristics of electromagnetic spectrum?

The characteristics of the electromagnetic spectrum are the propagation features and the amount of information, which signals can carry. In general, signals sent using the higher frequencies have shorter propagation distances but a higher data-carrying capacity.

What are the 5 uses of radio waves?

They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys. (For a fuller treatment, see electromagnetic radiation: Radio waves.)

What is the highest frequency?

Gamma rays have the highest frequency in the electromagnetic spectrum. They have a frequency of the order of about 1020 to 1022 Hz.

What is the lowest frequency wave?

Radio waves have the lowest frequency.

What color has the longest wavelength?

On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
