EM Spectrum
X-ray
The wavelength for x-rays is between 0.01 to 10 nanometers. The rays have enough energy to ionise atoms and disrupt molecular bonds and can be harmful to any form of living tissue. It is used for photography of bones, to check whether there are any cracks/ fractures.
-
Gamma Ray
Gamma rays are waves with incredibly high energy. It has the highest wavelength across the spectrum, between 300 GHz to 3 kHz. The high energy is utilised well with medical facilities for things like killing cancer cells. These waves have high frequencies and low wavelengths.
-
Ultraviolet
The wavelength for ultraviolet rays is between 10 to 400 nanometers. This ray is invisible to human eyes, however, some insects like bumblebees can see this ray. It is very harmful and is completely absorbed by the atmosphere. This ray is used most commonly in fluorescent lighting
-
Visible Light
Visible light is the only wave on the EM Spectrum that is seen by us humans. It is between 390 and 700nm is the typical wavelength from which a human responds to. It is the light we see in our everyday lives.
-
Infrared
The wavelength for infrared rays is between 700 nanometers to 1 millimetre. This ray is invisible to the human eye. Infrared rays can be used for thermal tracking of humans/ animals and can be used to see their heat pattern, it is also used for night vision cameras.
-
Microwave
Microwaves are a higher frequency version of radio waves. The wavelength is between 300 MHz and 300 GHz These waves are mostly found in transmitters and the microwaves used to heat food.
-
Radio Waves
The wavelength for radio waves is between 1 millimetre to 100 kilometres. This wave can't be seen by the human eye. These waves are used for communication and are also used in televisions and radios.
