My benchmark project is based on How fast sound waves can go through air, liquid, and solids. I found out that sound waves travel fast in water than is air, because when it's in the air it will go just everywhere, but in water it will stay together, so when it does it will go a lot faster.
Sound waves can travel through water and air for a long time and really fast, in air the sound waves can travels up to 340m per second and 1,224km per hour would be the average speed. In sea water sounds waves can travel up to 1,531m per second and 5,551km per hour. Sound waves can make a big impact on thing, for an example if a sound wave is going 340m per second into chair it would mostly likely have a lot of impact on the chair, but if you do a sound wave to giant bolder then did a sound wave at 340m per second then it would make that much of an impact on it maybe just a couple of cracks but not to much damage. Sound waves can create waves and movements in the earth, they can make earthquakes. The 3 letters that are important to movement is T: time, D: distance, and V: mass. Sound waves can come from sounds of music when it comes through the speakers and if you look closely at the speaker you can see it moving and that movement releases sound waves so people can hear the music come out of the speaker. Also sound waves and vibration go through the ocean when something moves in it for an example a boat. Solid particles are more connected than liquid and gas, so sound waves goes through solid things a lot faster than liquid and gas. Sound is a mechanical, it is a vibration of particles that go back and forth, they are also parallel lines that transport through energy.
