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.

Resource focuses on the relationship between the frequency, wavelength and speed of light. Has a link to an interactive activity relating frequency, wavelength, and energy.

Using a question and answer format, this page discusses the question: "Is the Speed of Light Constant?" Discusses some of the history and experiments performed with light and the conclusions drawn from those findings.

Did you know that light is a form of energy and always travels in a straight line? Discover some more interesting facts about light.

Kids learn about the science of light. Energy made of waves and particles called photons traveling at the top speed in the universe. What is refraction? The difference between transparent, translucent, and opaque.

In this kindergarten lesson, students will learn the importance of turning off lights when they are not being used.

Kids learn about photons in the science of physics, the particles of energy that make up light including properties and how they interact with matter.

In this video from the Encyclopedia of Physics Demonstrations, students will observe how a laser beam is trapped in a water jet because the light reflects against the surface of the water. [1:03]
