How-To Themes. Opt for a how-to theme if you want your students to research key steps in a process, according to the Common Core State Standards Initiative. Tell your class that the topics must relate to social studies, science, history, literature, technology or business.
In which kind of wave do the particles of the medium move at right angles to the direction in which the wave is traveling. Transverse. In what way do the particles in the wave move when surface waves combine the properties of transverse and longitudinal waves.
Mechanical Waves: Three Types Mechanical waves require a physical medium. The particles in the medium can move in two different ways: either perpendicual or parallel to direction of the wave itself. In a longitudinal wave, the particles in the medium move parallel to the direction of the wave. In a transverse wave, the particles in the medium move perpen-dicular to the direction of the wave. A surface wave is often a combination of the two.
