Waves show up in many different forms. In the last lesson we saw how the graph of a wave (a sinusoid) can be used to visually represent the motion of a mass on a spring or a pendulum.

But there are also real, physical waves (mechanical waves). You can see physical waves travel through water, strings and other materials. There are other physical waves as well, like sound waves and light waves. In this lesson we'll get an overview of waves and look at transverse and longitudinal waves, wave speed, frequency and period. In the next lessons we'll focus on sound and standing waves
