The use and importance of radio waves

  1. 1. By Justin Henry
  2. 2.  Radio waves are predominantly used for transmitting signals, enabling communication back and forth from great distances. These waves can be transmitted as far out as outer space or a short as several millimetres. In broadcasting radio waves are transmitted from specific locations to many others over limited distances. Theses waves carry signals for television, mobile phones and many other technologies that are used today. It is important to understand how much we rely on radio waves. Many of our information and key communication technologies use radio waves to allow us to benefit from them.
  3. 3.  Wi-Fi follows one of the key characteristics of radio waves. With Wi-Fi being wireless it allows user to connect to the internet without wired in technologies such as the computer to a cabled connection. As a connecting technology it gives the users the ability to interact through a variety of media. Radio waves are transmitted and received in the same way just like a walky- talky or 2way radio is.
  4. 4.  Mobile phones have become one of the most used technological devices in this last decade. With the aid of radio waves communication is possible from one device to many but most often to one. Just like regular cordless phones, mobile phones are radio transmit receivers. Radio waves carry these phone signals which allow text messages and phone calls to reach their designated receivers. Not only do radio waves provide us with those things they also provide us with wireless internet and 3G.
  5. 5.  Television has been the one of the most important medias in the last several decades. Its impact on the way we use media as whole has become more visual since it was invented. Radio waves carry the television signals and transmit them further as radio waves have the largest wavelength. This allows television to be broadcasted through satellite as radio waves can pass through the Ionosphere.
  6. 6.  We use wireless technologies everyday of our lives. We use them casually as well as purposely and benefit from their use of radio waves. From internet to mobile phones we regularly depend on wireless connectivity. We use radio waves for opening garage doors and car doors that require wireless key to open them. Also the use of radio waves are implemented in the use of Bluetooth, live news reports and internet during flights.
  7. 7.  Radio astronomy is the study of what happens amongst celestial object such as stars, planets, star clusters and galaxies. Radio waves are detected using large radio antennae to produce images of all that can’t be seen with regular advance telescopes.
  8. 8.  Radar uses radio waves to detect an objects direction distance and speed of which it travels. Radar has been considerably used in sea warfare during the recent wars. In modern use it has been used away from the battlefields for exploration. It has been found useful in ocean surveillance as well as marine radars. Radar is also used for weather monitoring.
