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.

This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.

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

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,...

[Free Registration/Login may be required to access all resource tools.] Students learn what an electromagnetic wave is, gain a feel for the main parts of the spectrum, and work on problems involving basic properties of electromagnetic...

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

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

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.
