What is wavelength of electromagnetic radiation?

Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave. A wavelength is the distance between two consecutive peaks of a wave. This distance is given in meters (m) or fractions thereof. Frequency is the number of waves that form in a given length of time.

What is gamma rays in electromagnetic waves?

Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells.

Where is gamma rays found?

These are found in all rocks and soil and even in our food and water. Artificial sources of gamma radiation are produced in fission in nuclear reactors, high energy physics experiments, nuclear explosions and accidents.

What are facts about the electromagnetic spectrum?

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands,…

What is the meaning of electromagnetic spectrum?

electromagnetic spectrum. noun. the entire spectrum, considered as a continuum, of all kinds of electric, magnetic, and visible radiation, from gamma rays having a wavelength of 0.001 angstrom to long waves having a wavelength of more than 1 million km.

What is the Order of the electromagnetic spectrum?

The electromagnetic spectrum encompasses all types of electromagnetic radiation. From longest wavelength/lowest energy to shortest wavelength/highest energy, the order of the spectrum is radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray.

What is the purpose of the electromagnetic spectrum?

This is the first indication of the existence of the entire electromagnetic spectrum. Nonetheless, the main significance of the electromagnetic spectrum is that it can be used to classify electromagnetic waves and arrange them according to their different frequencies or wavelengths.
