ELECTROMAGNETIC WAVES Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa —the two are linked. These changing fields form electromagnetic waves.

Milli-Sievert (mSv) is a form of measurement used for radiation. Astronauts are exposed to ionizing radiation with effective doses in the range from 50 to 2,000 mSv . 1 mSv of ionizing radiation is equivalent to about three chest x-rays. So that’s like if you were to have 150 to 6,000 chest x-rays.
Read moreHow is the electromagnetic spectrum used in space?
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas .

Read moreWhat is electromagnetic spectrum and its uses?
NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond . When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy.
Read moreWhat is electromagnetic spectrum Class 11?
Electromagnetic spectrum. Electromagnetic spectrum. When all the electromagnetic radiations are arranged in order of increasing wavelengths, and decreasing frequencies the complete spectrum is called electromagnetic spectrum as shown below: Limitations of this theory.
Read moreWhat is the electromagnetic spectrum answer?
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength . The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.
