Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

An introduction to the concept of the visible light spectrum provided in an animated format.

How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change....

An online exploration where students learn the basics about light and the properties of waves and the electromagnetic spectrum. Students will also learn how to measure wavelength and frequency so they can understand the electromagnetic...

This animation discusses light and the properties of light in a storybook format. The animations cover the colors of the rainbow (ROYGBIV) along with prisms, light waves, reflection, and refraction.

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

[Free Registration/Login Required] Are there colors we don't see? This simulation addresses that question by exploring light as an electromagnetic wave. Learn how the electromagnetic wave relates its wavelength and frequency to the...

This lab is designed to allow students to look at the factors affecting the location of different colors formed by diffraction grating.

This interactive tutorial illustrates how spectrometry is used to study, identify, and quantify materials.
