The animation portrays a medium as a series of particles connected by springs. In this type of longitudinal wave the particles of the medium vibrate in a direction parallel to the direction of energy transport.

This Nobel website on the life and scientific work of Robert A. Millikan includes a biography, images, and internet resources for further reading and research. Also included are the 1923 "Presentation Speech" which praised Millikan's...

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

Link to nine major physics topics and dig deeper into the content. Find out about the work of scientists in each field and see example physical science experiments.

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...

Take a special trip to the Atlanta Symphony Orchestra with GPB Education! This interactive virtual exploration offers students a behind-the-scenes experience as they learn about the science of sound and the preparation it takes to put on...

This digital textbook covers core physical science concepts and includes interactive features, real world examples, and videos.

Here is an introduction to the concept of waves and wavelike motion people experience anywhere and everywhere.

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...

A student learning module with a focus on the relationship of temperature and salinity with density, ocean-influenced weather patterns, and how light and sound move through ocean water.

An interactive resource on diffraction, interference and superposition with descriptions, animations, and questions.

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

[Free Registration/Login may be required to access all resource tools.] Discusses the definition of energy, the SI unit, and the seven different forms of energy.

Two wave graphs depicting a sine wave and relating the various characteristics (wavelength, amplitude, frequency, and period) of a wave to each other. The site includes an interactive JavaScript form in which the visitor enters one...

A collection of video lectures created by University of Sheffield to excite young students about topics in physics in elementary school. The course covers topics like forces, gravity, magnets, sound, light, space travel, and the solar...

A model for examining the simultaneity of two events where the relative velocity and the wave source, either light or sound, can be manipulated.

While some of the pages on this site have yet to be filled, the pages that are complete are comprehensive. For example, pages on friction, heat, and the Doppler effect are illustrated and explain relevant formulas. A biography page...

The Nobel Foundation provides a biography of Bragg. This site focuses primarily on his activities and accomplishments as a scientist.

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will investigate examples of kinetic and potential energy and their transformations.

At this site from the Nobel e-Museum, you can read about the scientific work of Lord Rayleigh (1842-1919 CE). This article includes information on his education and experiments with light and sound waves.

Review the key terms and skills related to wave interference, including how to predict wave interference patterns.
