The video tutorial introduces longitudinal waves, explaining that they are waves where the displacement of the medium is parallel to the direction of wave propagation. It covers the anatomy of these waves, including compressions and rarefactions, and how to measure their wavelength and frequency. Examples such as sound waves and seismic P waves are provided. The video concludes with an invitation to explore more about waves through additional resources.

What creates compressions in a longitudinal wave?

• Particles moving randomly

• Particles coming closer together

• Particles remaining stationary

• Particles moving apart

How is the wavelength of a longitudinal wave measured?

• From trough to trough

• From rarefaction to rarefaction

• From compression to compression

• From crest to crest

What does the frequency of a longitudinal wave indicate?
