What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson then explains wavelength using a rope to make waves.

Radioactive pollutants can enter the body through ingestion, inhalation, absorption, or injection. The last lesson in a series of 36 introduces pupils to radioactive pollution. They study its sources, both natural and man-made, its...

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...

An in-depth encyclopedia article from Wikipedia on waves gives a definition for what a wave is. Other content in the article includes a list of examples and characteristics of waves, information about the difference between transverse...

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.

Online physics text that illustrates and explains the various characteristics of waves such as amplitude, period, frequency, wavelength, and speed. Includes interactive exercises.

Describes the characteristics of light, presents two formulas for calculating its wavelength, and provides a table of the different wavelength ranges across the electromagnetic spectrum.

Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

This site from Cornell University provides a very short, very telling comparison of matter and charge. This is a good site to check out on the subject, with a chart diagram to help with further information.

This Florida State University page introduces light as an electromagnetic wave and discusses the frequency and wavelength range of the various regions of the electromagnetic spectrum. Includes links to some interactive Java applets.

A short sketch of the life and work of Thomas Young (1773-1829 CE). Traces early upbringing and education and his scientific discoveries and contributions.

This site details what radiation is, the physics of radiation, and radiative transfer as it occurs in nature. Content explores the electromagnetic spectrum, electromagnetic waves, properties of radiation, and solar radiation.

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

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

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...

Simulation that shows the diffraction of light through single or multiple slits. Simulation allows modification of the number of slits, slit width, slit separation, and the wavelength.

From a course titled "Structure and Interpretation of Signals and Systems." A discussion of the entire radio spectrum, listing wavelength and frequency values for its various parts. The uses of each region of the radio spectrum is...

Learn about light properties through practice with formulas. This resource shows the relationship between the speed of light, its wavelength, and its frequency. A fairly simple, but important relationship.
