Angles, parallel lines, and transversals are explained through examples and a video lesson. [1:01]

Students explore the characteristics of both transverse and longitudinal waves.

[Free Registration/Login may be required to access all resource tools.] Covers three types of mechanical waves - transverse, longitudinal, and surface - and their characteristics. Includes labeled illustrations and two video animations.

Consider two parallel lines that are intersected by a transversal, and when it crosses the two others, many different angle pairs are formed. See the special properties of the angle pairs in this interactive.

This physics tutorial helps students categorize waves based on distinguishing, observable characteristics.
