Waves are vibrations that transfer energy from place to place without matter being transferred. Think of a Mexican wave in a football crowd: the wave moves around the stadium, while each spectator stays in their seat only moving up then...

This video reviews what harmonic motion is then provides definitions of all the components of the wave. Real world examples of simple harmonic motion are shown. Students will learn how to calculate frequency using a pendulum and a spring.

This video engages students by asking questions and showing phenomena that relate to simple harmonic motion. The program provides examples and demonstrations using “singing” glasses, violin and piano sounding boards, oscillations in...

Internal tides, or internal waves, can reach hundreds of feet underneath the ocean surface, but might only be a few inches high on the surface. Even though they’re underwater, NASA can see these tides from satellites. They...
