Quick Answer: What are the 7 waves in the electromagnetic spectrum?

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

What are electromagnetic waves Class 7?

Basically, there are 7 different types of Electromagnetic Wave, these are categorized by in terms of frequency and wavelength. These 7 types of waves are as follows: Radio Waves, Microwaves, Infrared, Visible, Ultraviolet, X-Ray, Gamma Rays.

What are the 7 wavelengths of light?

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.

Which of the 7 major region of electromagnetic spectrum have the highest frequency?

The waves that live in the gamma ray section have the highest frequencies and smallest wavelengths of all the EM waves. In fact, there is no lower limit to the wavelength of a gamma ray. Some have wavelengths that are smaller than an atom! Gamma rays are emitted naturally from things undergoing radioactive decay.

What are electromagnetic waves Class 8?

Electromagnetic waves are also known as EM waves. Electromagnetic radiations are composed of electromagnetic waves that are produced when an electric field comes in contact with the magnetic field. It can also be said that electromagnetic waves are the composition of oscillating electric and magnetic fields.

What are the wavelengths of the visible spectrum?

The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.

How many types of waves are there?

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.

Which of the following are electromagnetic waves?

The correct answer is option 1 i.e Infrared rays. Waves that consist of vibrating electric and magnetic fields are called electromagnetic waves.

The examples of electromagnetic waves are:

  • Radio waves.
  • Microwaves.
  • Infrared waves.
  • Visible light.
  • Ultraviolet.
  • X-rays.
  • Gamma rays.

What comprises 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.

Which EM waves has the longest wavelength?

Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.

Which wave has lowest frequency?

Radio waves have the lowest frequency.

What are electromagnetic waves Class 12?

Electromagnetic waves are those waves in which electric and magnetic field vectors changes sinusoidally and are perpendicular to each other as well as at right angles to the direction of propagation of wave.

What are the 3 different types of light waves?

Light waves have different forms: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Sunlight is a source of visible light and ultraviolet radiation. X-rays and gamma rays are used in medical diagnosis, cancer treatment, and security.
