WebIn sea water, radio waves don't travel too far but microwaves might do better because sea water isn't a "good" conductor any more at those frequencies. On the other hand, sound waves travel through water very well so submarines use sonar rather than radar. Click Here to return to the search form. WebApr 1, 2024 · An underwater transmitter uses an acoustic speaker pointed upward to the surface. The transmitter sends sound signals, which travel as pressure waves. When these waves hit the surface, they cause tiny vibrations. Above the water, a radar continuously bounces a radio signal off the water surface. dalkeith high school holidaysWebThe channeling of sound waves allows sound to travel thousands of miles without the signal losing considerable energy.
