Sound Waves Notes:
There are two types of sound waves.
- S-waves (sheer): Like a wave in the ocean.
- S-waves is refereed as secondary waves.
- P-waves (pressures): By pushing the molecule in front of it to transfer it.
- P-waves are refereed as primary waves.
- Waves can travel and cause Earthquakes.
- In order for wave sound to travel vibration and median (matter) to travel far.
- The closer things are compressed the faster sound travels.
- Sound is directional, it only travels one way.
- Higher density will have faster traveling sound.
- Sound travels faster in water, because the molecules are closer in the water which transfer the sound faster.
- Water has higher density meaning the sound travels faster.
- Though sound goes faster in the ground than the water, because the ground in more dense than water.
SOFAR:
- In the middle, the sound travels the slowest which is called the so-far channel.
- SOFAR travels very slow but it travels a very far distance.
- Sounds reflect against each other in the SOFAR Channel.
- Sound does not travel in the shadow zone.
