making a wave

Today in our lab we had a cylinder of water and some tuning forks and my group figured out a cool thing. When we struck the tuning forks and placed them in the water, the water splashed and made some waves. The tuning forks with lower frequencies didn't make those waves because they didn't have enough amplitude to move the water. The thicker and longer the tuning fork was the bigger the waves. The water splashed onto the cylinder of water and was quite amusing to me and my other group members. The sound waves from the tuning fork made a vibration and amused us by the splashing water. Although the lab was fun, that part was even more fun.

Another thing that happened today that created waves was when I hit the rubber stopper against the plastic tube. The sound varied with the material I used to hit the tube. When I hit it with the rubber stopper, the noise was quieter compared to when I hit it with the wooden part of the pencil. The different frequencies changed the sound that we heard when I hit the tube.
