Your question: What are two natural sources of electromagnetic radiation?

solar radiation, in other words natural radiation that originates from the sun. terrestrial radiation, in other words natural radiation emitted by the Earth’s surface.

What are the two sources of electromagnetic radiation?

Sources of Electromagnetic Radiation

  • solar radiation, in other words natural radiation that originates from the sun.
  • terrestrial radiation, in other words natural radiation emitted by the Earth’s surface.
  • artificial radiation originating from a remote sensing system.

What is natural electromagnetic radiation?

Natural EMR/EMFs (cosmic microwaves, infrared, visible light, ultraviolet, gamma rays) and several forms of artificially triggered electromagnetic emissions (such as from light bulbs with thermal filaments, gas discharge lamps, x-rays, lasers, etc.) are not polarized.

What are 2 examples of electromagnetic energy?

They include:

  • Radio Waves.
  • TV waves.
  • Radar waves.
  • Heat (infrared radiation)
  • Light.
  • Ultraviolet Light (This is what causes Sunburns)
  • X-rays (Just like the kind you get at the doctor’s office)
  • Short waves.

What are 5 examples of electromagnetic radiation?

List five examples of electromagnetic radiation. Electromagnetic radiation is a form of energy that exhibits wavelike behavior as it moves through space. Examples are: radio waves, microwaves, infrared light, visible light, ultra violet, x-rays, and gamma rays.

What is the main source of electromagnetic waves?

The most important source of electromagnetic waves on Earth is the sun. Electromagnetic waves travel from the sun to Earth across space and provide virtually all the energy that supports life on our planet. Many other sources of electromagnetic waves depend on technology.

What are the types of electromagnetic radiation?

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

What are the major sources of electromagnetic fields?

They are generated by natural phenomena like the Earth’s magnetic field but also by human activities, mainly through the use of electricity. Mobile phones, power lines and computer screens are examples of equipment that generates electromagnetic fields.

What are electromagnetic radiation in chemistry?

Electromagnetic radiation consists of two perpendicular waves, one electric and one magnetic, propagating at the speed of light (c). Electromagnetic radiation is radiant energy that includes radio waves, microwaves, visible light, x-rays, and gamma rays, which differ in their frequencies and wavelengths.

What are the sources of electromagnetic waves in the Earth’s environment?

Many of the EM waves present in Earth’s environment come from the Sun. The Sun’s high temperature allows it to give off countless EM waves. Other stars give off as many EM waves as the Sun, but because these bodies are so far away, fewer of their EM waves reach Earth.

What are the three examples of electromagnetic radiation?

Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices.

What are 3 examples of electromagnetic waves?

Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength.

What is electromagnetic radiation Class 11?

Electromagnetic radiation is a flow of energy in which electrical and magnetic fields vary simultaneously. Radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma rays are all electromagnetic radiations. … Its wave nature is represented by its velocity, frequency and wavelength.

Which of the electromagnetic radiation is radioactive?

A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. … Gamma rays, X-rays and the higher energy range of ultraviolet light constitute the ionizing part of the electromagnetic spectrum.
