Question

Name the electromagnetic waves in the wavelength range $10\,mm$ to ${10^{ - 3}}\,mm $. How are these waves generated? Write their two uses.

Answer 1

Hint:Electromagnetic waves are created in between electric field and magnetic field. In other forms it can be called the oscillation of electric and magnetic fields. In this question given some wavelength of the electromagnetic waves and for this wavelength we have to find out how these waves are generated and we have to mention any two examples which are of electromagnetic waves.

Complete answer:
Electromagnetic waves are in groups which form the electromagnetic spectrum in common properties. Electromagnetic waves are also called transverse waves which can be travelled in vacuum also. These waves not only travel in air but also travel in vacuum space also; this will be proved that the waves are radio from the light.

Here the length of the electromagnetic waves is $10\,mm$ to ${10^{ - 3}}\,mm$ is called radio waves. Radio waves are generated and propagated by radio transmitters. These waves are then received by a radio receiver (tuned to a particular frequency/wavelength using a radio antenna) which then converts these into mechanical waves which are played through radios and different sounds. Uses of electromagnetic waves are the formation of astronomical objects and it is used in diagnostic tools in medicine.

Note:Some of the examples of electromagnetic waves are, radio waves, visible light, x rays these are the examples. Already in the solution part we have discussed the electromagnetic waves and their examples but the electromagnetic waves are differing from each other from the other wavelength.
