Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates . Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist. It is one of the most important principles that governs everything around us.

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 the structure of an electromagnetic wave?
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!
Read moreWhat is electromagnetic wave with diagram?
Electromagnetic waves are shown by a sinusoidal graph . It consists of time-varying electric and magnetic fields which are perpendicular to each other and are also perpendicular to the direction of propagation of waves. Electromagnetic waves are transverse in nature.
