Insights on Different Spectrums of Light
The electromagnetic spectrum of light comprises the different frequencies and the respective photons they emit during radiation. The wavelength of this spectrum ranges from thousands of kilometers to smaller than the size of an atom. Students who do write a research thesis on the electromagnetic spectrum look for experts who can write my paper.
Discovery of the Electromagnetic Spectrum
For a long time, it was believed that light visible to humans was the only component of the electromagnetic spectrum. Light-based experiments by scientists led to the discovery of different electromagnetic spectrums. As of now, there are more than six different electromagnetic spectrums that can be classified based on their wavelengths.
Here are the following classifications of the electromagnetic spectrum based on their frequency
Gamma Radiation: This spectrum is generated during the radioactive decay of the atom's nucleus. They have the shortest frequency among various spectrums of light. The natural gamma radiation source forms the radiations obtained from cosmic ray particles. The ionizing radiation of gamma rays can be artificially obtained on a large scale during nuclear fission explosions. Due to their ionizing penetrating nature, they are widely used in spectroscopy
X-Ray: They are another penetrating form of electromagnetic radiation; they have a longer wavelength than gamma rays. X-rays are most used in medical tests. When the human body is exposed to x-ray, different tissues and organs absorb x-ray with varied intensity. The calcium absorbs the highest amount of x-ray because of which x-ray are most used to study the skeletal system of the patients.
Ultraviolet Radiation: They are non-ionizing radiation emitted by astronomical bodies such as the sun. The Earth's ozone layer absorbs most of the UV radiation emitted by the sun.
Visible Light: This is the spectrum that is visible by human light; when this light passes through optical apparatus such as a prism, we can witness the different spectrums of visible light based on their frequency
Infrared Light: This light spectrum has a larger wavelength than visible light. It is mostly used in thermal imaging and developing night vision equipment.
Microwave Radiation: Microwaves are those waves in the electromagnetic spectrum which have a higher wavelength than infrared waves but are shorter than radio waves. They are mostly used in cooking appliances and communication.
Radio Waves: This type of electromagnetic spectrum has the largest wavelength. This wave travels at the speed of light and can transmit information over large distances. They comprise charged particles that, when energized, travel to large distances. For effective communication, the transmitter and receiver should have a similar frequency. When radio waves travel in a vacuum, they travel with the speed of light, and when they travel through a medium, they slow down, due to which they are used for space communications.
