The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.

This lesson will introduce light waves and describe how a particle can travel as a photon or a wave. It is 4 of 4 in the series titled "Light Waves."

A few short, interactive activities on light waves can be found on this site. Numerous others links and teacher resources are posted here as well. A good background on light is offered for teachers.

How can scientists lump heat, light and sound together when investigating properties and behaviors? This learning module will address that question through a series of activities.

This interactive activity adapted from the University of Utah's ASPIRE Lab provides an overview of the characteristics and properties of various types of waves, including light waves, sound waves, and water waves.

[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...

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

In order to understand refraction, students will explore the factors that affect the speed at which a light wave is transported through a medium.

[Free Registration/Login Required] An informational text about light waves and how they travel. A question sheet is available to help students build skills in reading comprehension.

Students will investigate the properties of light waves. They will learn about the different types of electromagnetic waves and mechanical waves, and investigate the phenomena of reflection, refraction, interference, and diffraction.

Make waves with a dripping faucet, audio speaker, or laser. Add a second source or a pair of slits to create an interference pattern.

Physiclips thoroughly presents mechanics concepts about light with animations and film clips. Learn about light and color, wavelengths, speed of light, electromagnetic waves, Young's experiment, and photons.
