Your question: What is the source of electromagnetic radiation?

Answer 1: The most obvious source of electromagnetic energy and radiation is the sun. The sun provides the initial energy source for much of the remote sensing of the Earth surface. The remote sensing device that we humans use to detect radiation from the sun is our eyes.

What are two natural sources of electromagnetic radiation?

EMF is short for electromagnetic fields or sometimes known as electromagnetic radiation (EMR) or electromagnetic energy (EME). Electromagnetic fields are present everywhere in our environment – the earth, sun and ionosphere are all natural sources of EMF.

What is the major source of all electromagnetic radiation on Earth?

Our Sun is a source of energy across the full spectrum, and its electromagnetic radiation bombards our atmosphere constantly. However, the Earth’s atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life.

What is the simplest source of electromagnetic waves?

Electromagnetic waves are generated due to changes of electric and magnetic fields associated with oscillating charges.

What are some sources of electromagnetic radiation that we use every day?

Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.

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 is electromagnetic radiation in simple words?

In layman’s terms electromagnetic radiation is light that travels by oscillating in waves at a constant speed carrying energy. … In layman’s terms, light travels by oscillating in waves at a constant speed carrying energy – interactions with objects vary depending on the energy these waves carry.

What is the source of electromagnetic radiation for passive sensors?

Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors. Examples: film photography, infrared, charge-coupled devices, and radiometers.

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.
