The study of waves is not a quacking matter! Watch as a duck manipulates the behavior of its waves through its motion. Graphs show the frequency and wavelength of the waves. 

Discover the secrets used by scientists to measure mechanical waves. Young physicists learn about measurable wave qualities—amplitude, wavelength, and frequency—by watching and listening to a video discussing longitudinal and transverse...

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes. 

Stars are too hot to visit, so how do we know what different stars are made of? An enlightening simulation uses a spectrum graph to show the various electron emission and absorption reactions. Scholars experiment with both helium and...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...
