Thread: Sonar Quiz #12

You guys know more about Sonar than you realize....

Now, the boring "technical explanation"...
___________________________________

The sound pulse travels thru the water in a sine wave...(Below are 2 examples of sine waves) ...



Sine wave - Wikipedia, the free encyclopedia

Within a sine wave ...there are measured sections called wave lengths...

1 wave length is defined as the distance over which the wave's shape repeats...see below...



Wavelength - Wikipedia, the free encyclopedia

The tighter these individual wave lengths are together - the higher the frequency of the sine wave becomes...

Also, the tighter these individual wave lengths are together - the more of the actual sine wave is able to hit the "target"...

Thus...the higher the sine wave - the more of the sine wave that hits the target - the more reflections that can be returned = the more data returned = the more detailed the image....
