An interactive simulation that teaches about electromagnetic radiation, dipole radiation, and electric fields by observing the effects of changes in sinusoidal, circular, and linear motion on the outward propagation of radiation. This...

Electromagnetic radiation waves are found all around us. Young researchers will discover more about these energy waves with these highlights.

Briefly explains the different types of radiation in the electromagnetic spectrum.

Find out how energy, frequency, and wavelength are related in terms of the electromagnetic spectrum.

For this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.

This lesson discusses how electromagnetic radiation transfer the sun's energy to earth. This lesson will also talk about the eight types of electromagnetic waves in the electromagnetic spectrum and how each type is used or found in our...

Describes how terahertz radiation, or T-rays, are used to detect hidden objects, including revealing a hidden painting, illegal materials in a piece of luggage, and defects on a space shuttle.

In this very detailed lesson plan from NASA, students investigate wavelength and frequency within the electromagnetic spectrum.

This video segment from Swift: Eyes through Time introduces and explains theories of the origin of gamma-ray bursts. [4:11]

[Free Registration/Login may be required to access all resource tools.] Students investigate the fundamentals of light including its source, how it is defined for measurements, how we perceive color, and the situations that make an...

Practice questions over infrared and ultraviolet/visible spectroscopy questions.
