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.

Kids learn about the science of the light spectrum. Wavelengths and frequencies of the electromagnetic waves including visible light, primary colors, and subtractive colors.

[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...

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...

In this lesson plan, 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...

In this activity, students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources.

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

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.
