Students are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

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 online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

The dualistic nature of light is discussed. The photoelectric effect and the Davisson-Germer experiment are contrasted as empirical evidence supporting each of the two views - particle and wave - of the nature of light. The photoelectric...

A tutorial on the electromagnetic and visible spectra. Discusses dispersion and how perceptions of white and black are related to the visible light spectrum.

A study guide for concepts related to wave optics.

Learn all about stars and the electromagnetic spectrum in this series of activities.

This illustrated physics tutorial explains the electromagnetic and visible spectra of light using illustrated examples and interactive practice problems.

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.

NASA related site shows the entire Electromagnetic Spectrum. Provides a brief description of the expansive colored spectrum as well as a related link that provides more details.

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.

Lucianne Walkowicz shows us the waves just beyond our perception: microwaves, radio waves, x-rays and more. [5:58]

Students will focus on the interaction of sunlight with atmospheric particles to produce blue skies and red sunsets.

A gallery of astronomy images which depict galaxies, comets, the moon, planets, nebulae, supernovae as seen in various regions of the electromagnetic spectrum. Each image in the gallery is described. Fascinating!

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.
