Short Essay On Radio Waves

What are waves?

Scientifically, waves transfer energy through vibration from one area to another. Some types of waves need a medium in which to travel through; these waves are called mechanical waves. Other types of waves do not need a medium in which to travel through, they can travel in empty space; these waves are called electromagnetic waves. Mainly, there are two types of how the particles in the waves vibrate, they are called transverse waves and longitudinal waves. The particles in transverse waves vibrate in an up and down pattern. However, particles in longitudinal waves travel in the same direction the wave travels (back and forth movement). The properties of waves are called amplitude, wavelength, and frequency. The amplitude is the measure of the distance of the wave from its normal rest position. The distance between any point on a wave and the same point on the next wave is called the wavelength. The number of waves produced in one second is called its frequency.

The history of radio waves:

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic radiation, but how and who created and innovated the radio waves?

In 1860,

As for its pros, it benefits better communication, navigation, and increases accuracy. In communication, not only people in in earth can receive and send signals to each other, but also astronauts are able to send and receive signals from outer space to earth, and the opposite. For better navigation, radio waves are used to indicate and determine the exact location of a device. In increasing the accuracy, using radio waves allows the controlling of devices that are far away from the source with accuracy improved. As for the cons of radio waves: because radio waves have very low frequencies; they are not harmful at all to living organisms that are often exposed to the radio waves because they do not have enough energy to harm these
