Write is the difference between the sound waves and the waves on the surface of the water body? |
| Answer» <html><body><p>There is one crucially important difference between waves bumping over the <a href="https://interviewquestions.tuteehub.com/tag/sea-638310" style="font-weight:bold;" target="_blank" title="Click to know more about SEA">SEA</a> and the sound waves that reach our ears. Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward. Waves like this are <a href="https://interviewquestions.tuteehub.com/tag/called-907796" style="font-weight:bold;" target="_blank" title="Click to know more about CALLED">CALLED</a> transverse waves. That just means the water vibrates at right angles to the direction in which the wave travels. Sound waves <a href="https://interviewquestions.tuteehub.com/tag/work-20377" style="font-weight:bold;" target="_blank" title="Click to know more about WORK">WORK</a> in a completely different way. As a sound wave moves forward, it makes the air <a href="https://interviewquestions.tuteehub.com/tag/bunch-403868" style="font-weight:bold;" target="_blank" title="Click to know more about BUNCH">BUNCH</a> together in some places and <a href="https://interviewquestions.tuteehub.com/tag/spread-1222907" style="font-weight:bold;" target="_blank" title="Click to know more about SPREAD">SPREAD</a> out in others. This creates an alternating pattern of squashed-together areas (known as compressions) and stretched-out areas (known as a rarefactions). In other words, sound pushes and pulls the air back and forth where water shakes it up and down. Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.</p></body></html> | |
