Answer:
Longitudinal Waves and Transverse Waves Mechanical waves are categorized by their type of motion and fall into any of two categories: transverse or longitudinal. Note that both transverse and longitudinal waves can be periodic and Like transverse waves, longitudinal waves do not displace mass. The difference is that each particle which makes up the medium through which a longitudinal wave propagates oscillates along the axis of propagation. ... Matter in the medium is periodically displaced by a sound wave, and thus oscillates.
Explanation:
(YOU HAVE TO DO YOUR OWN WORK, BUT I CAN HELP YOU COME UP WITH CONCEPTS AND TIPS)
*DONT write about climate change!!! Your work is going to seem basic, because a lot of people are going to be writing about that.
*DONT write about something most people are going to write about, you want to seem creative and you want to stand out (in a good way).
*Write about something YOU can relate to!!! Your essay will have more meaning and the professor/teacher will feel you worked harder on it.
*Stay on topic!!!!
*What are some things you should write about?? Think about something that is POSSIBLE to fix in the world.
*DONT make something up that isn't realistic to fix!! EXAMPLE; Earthquakes
