Transverse and Longitudinal Waves

Mr. Anderson explains transverse and longitudinal waves, using seismic waves to explore Earth's interior. He differentiates between mechanical and electromagnetic waves, highlighting that mechanical waves need a medium while electromagnetic waves do not. The video also covers wave polarization, showing how transverse waves can be filtered using polarizers. The tutorial concludes with a summary and a check on understanding the concepts.

What is the role of a medium in mechanical waves?

How do electromagnetic waves differ from mechanical waves?

What is polarization in the context of transverse waves?
