Unformatted text preview: teaching physics, there are other common usages of Doppler that may fly under the radar. Another usage of the Doppler Effect comes from a vital weather tool, the Doppler radar. All weather radars use radio waves to create an image designed to show where and how hard rain is falling. The Doppler radar, however, takes this concept a step further, as it also measures the frequency change in these radio waves . As a result, you not only see precipitation, but also wind speed and direction. Not only does this allow us to understand what is happening in the weather at that moment, but it gives us a great tool to predict what might happen concerning the weather in the near future. Doppler is just one example of how the ability to measure has revolutionized our knowledge of the universe through the use of physics.
