"WAVES!"

-Lately during class we have been doing exersises about waves. Waves are caused by vibration. We learned differnt types of waves and even what waves do. Longitudinal and transverse waves are they only two ive learned.I figured out that longitudinal waves move parallel through the medium. While a transverse wave moves at an right angle through the medium(middle point which waves travel through). Some difffernt parts of a transverse waves is the crest-(highest point of the wave) and the trough-( is the lowest point.). In addition the longitudinal wave has two total different parts called compression and rarefraction. Picture a slinky in your head. When the coils are close together is known as compression. When the cils are spaced out it is called rarefraction. In class we did an experiment with sand. sand was placed in a cup and hug 2 feet over 3 sheets of paper and was swung in a back and forth motion while the paper was slowly slid. We then traced our wave and labeled parts of it.

From these sites i leraned exactly how waves move. It gave great examples and the exersises we did in science was a great help. I also leraned waves are all around you. These are the most two common waves.From the second website i discovered that transverse waves cannot propagate in a gas or a liquid because there is no mechanism for driving motion. This is goingt o be interesting to find out more facts!
