Today in class, we talked about transverse and longitudinal waves. We also discussed the different types of waves that are used, such as light waves, radio waves, and water waves. We even used a sensor to determine the amount of energy used in each wave we made using a slinky per second. It was also the day when we found out we were having a quiz on waves!
