Discusses the history of the discovery and study of electromagnetism, the scientists who worked on it, the basic principle, how wavelength and frequency are related, and types of electromagnetic waves.

By the end of this section, you will be able to define pitch; describe the relationship between the speed of sound, its frequency, and its wavelength; describe the effects on the speed of sound as it travels through various media; and...

This site from Architectural Acoustics and Lighting provides a discussion of various factors affecting the acoustics of a given room. Room dimensions, the wavelength of the sound wave, the physical characteristics of the walls, the...

This physics tutorial explores forced vibration. Includes links to natural frequency, standing wave patterns and fundamental frequency and harmonics.

[Free Registration/Login may be required to access all resource tools.] In this learning module, compare characteristics and behaviors of transverse waves, including electromagnetic waves.

This hypertext physics course page illustrates and explains the Doppler effect. Users perform practice calculations for frequency shifts using the Doppler equation.

Acting as part of an overview on quantum theory, this section of the site answers the question, what is a wave? In addition to a definition, several examples and formulas are provided.
