In our tangible journey we have been able to find essential and fabulous machines such as bicycles, cars, helicopters, submarines, airplanes, jet skis, cameras and video cameras, compound microscope, satellites, among many other machines, which undoubtedly manage to facilitate the realization of a certain task in our lives.
On this occasion I wanted to talk about a wonderful device or electronic tool known as radar or speed control gun, this in order to continue to highlight that technological advances reach any aspect of our existence and that this feature is becoming stronger every day among us all.
Perhaps many of you have witnessed the use of this type of speed measurement device and applied either to heavy duty vehicles or light cars in order to control vehicle traffic, other extraordinary applications can be found in the fascinating world of sport as in tennis, in baseball, where, the speed with which the balls are thrown is considerable, either by being hit by the tennis racket or the baseball bat or by the fact of being thrown by the Piker at high speed as they could observe in the gif at the beginning of this article.
The principle used by these devices is the Doppler effect and thus the measurement of the change in frequency of certain electromagnetic waves such as radio waves or infrared, whose waves on impact with the object or body to be measured are reflected and return to the radar or speed control gun, and therefore the frequency of the waves reflected and received is different from the waves emitted, with that difference this device manages to obtain the speed of the object under study, either a vehicle, a tennis ball, soccer or baseball as you can see below in the following image gif.
With each step we have taken, we have been able to demonstrate that the science-technology nexus is truly intrinsic to each advance made in the area of technological applications, and that these have an increasing influence on all of us, regardless of the area of development in which we find ourselves.
It is fascinating to be able to observe and also measure the speed of a baseball thrown by a Pitcher, to put just one example of many others that we witness daily, the truth is that over time we will be reliable witnesses of each technological advance applied in any of our most everyday activities such as those outlined in this article and the measurement of the speed of a particular object or body present in our environment through a device of human creation with the help of science and technology.
Until another opportunity my dear and appreciated readers.
