If alien life does exist, what might it be like? Would it be simple forms of life such as bacteria,virusesor algae, or more advanced, multi-cellular creatures, perhaps even intelligent beings? Wouldaliensbe animals, plants or have characteristics of both? Would they have arms and legs ...
The Doppler effect is observed when the source of a particular set of waves is moving with respect to the observer. Suppose you are standing on the sidewalk, waiting to cross the street. On the far left side of your position, you see an ambulance racing in your direction. In this case,...
How does a DVL work? A DVL works by using the Doppler effect, which is the change in frequency of a wave due to the relative motion between the source of the wave and the observer. DVLs transmit a series of sound waves towards the sea bottom and then measure the frequency shift of ...
They also have a good idea why the Doppler effect occurs. And they've incorporated its principles into a variety of useful tools and gadgets. In this article, we'll examine everything Doppler: the man, the science and the technologies. But first we have to lay some groundwork. Because ...
How do digital scales work (ie. mass, gravity, and weight)? How can a star's luminosity be determined? How does the Doppler effect manifest itself in the light? How does a pigment affect light? Explain the working of nor gate using a transistor. What are the two conditions that must ...
Currently, the folks at Trijicon are building a new binocular downrange wind measurement system that makes use of a Doppler LINDAR engine. In effect, the system can measure wind velocity at long ranges. This system uses a laser doppler to measure particulates in the air at the target. ...
Then there are meteorologists who use Doppler weather radar when tracking weather systems like storms,hurricanesandtornadoesbecause of radar's ability to work in a range of weather conditions. Doppler radar, for example, can detect precipitation. ...
How does a barometer work?Question:How does a barometer work?Pressure Tube:A barometer is a tool that measures atmospheric pressure. This tool was invented by Italian physicist Evangelista Torricelli in 1644. The initial barometer was known as Torricelli's tube.Answer...
How does an excimer laser work? How do atom smashers work? How does pulse Doppler radar work? How can a magnetic field produce an electric current? How do longitudinal sound waves work? How does a current transducer work? How does special relativity make magnets work? How does a nuclear-po...
