reflection on the wave unit (how does the use and study affect social well-being)

In this unit I learned about 3 types of waves (sound waves, electromagnetic waves, seismic waves) I learned that sound waves can't travel through outer space because there is no medium. Another thing I learned was how waves travel and how they work. All waves go through a medium and they carry energy. The electromagnetic waves (ultraviolet, X-rays, infrared, microwaves, etc.) these are some of the electromagnetic waves. For next time I would do more of electromagnetic waves. I learned more things and some of them I didn't know before. Creating the seismograph was vary fun.
