1.Oscillations, Mechanical waves, and sound
Waves are responsible for basically every form of communication we use. Whether you're talking out loud, texting on your phone, or waving to someone in a crowd there's going to be a wave transmitting information. Learn about the basics of waves in this topic, then learn more about light waves in the topics below.
