[Free Registration/Login may be required to access all resource tools.] The speed of electromagnetic waves, their wavelengths and frequencies and how to calculate wavelength or wave frequency.

Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.

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.

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...

Through informational text, interactive activities, practice problems, and virtual simulations, students explore the properties of electromagnetic waves.

Students learn the basic properties of light--the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic...

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

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.

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...

This site details what radiation is, the physics of radiation, and radiative transfer as it occurs in nature. Content explores the electromagnetic spectrum, electromagnetic waves, properties of radiation, and solar radiation.

An indexing page for a physics department site about the wave properties of light that lead to interference.

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...

A video and a short quiz on how sound travels in waves, its properties, and how to measure it.

This article discusses the properties of electromagnetic radiation and photons.

Flip over this interactive OLogy card to find fast facts, questions and answers, and similar bite-size pieces of information about the properties and uses of lasers.

This site provides two activities that students can do in class. One uses mirrors to reflect light beams whole another is making a kaleidescope.

Students apply everything they have learned over the course of the associated lessons about waves, light properties, the electromagnetic spectrum, and the structure of the eye, by designing devices that can aid color blind people in...
