In this physics tutorial, focus on the refraction of light in great detail. Explore the conceptual and mathematical principles governing the bending of waves as they cross the boundary between two media.

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.

This resource provides information on light as well as links to additional sites on light and optics.

A very simple device to convert light into sound can be made by wiring a solar cell directly to headphones (or an earpiece). The solar cell converts light into electricity and the headphones convert electricity into sound. The limitation...

In this exploration, learners will investigate how light reflects off smooth surfaces, learn about angles of reflection, and apply that knowledge in a relay experiment.

In this lesson plan, students experience how light interacts with the environment by investigating relationships between shadows and light. Students will experiment with light by observing how light travels through materials and distances.

Students will determine the effect of placing objects made with different materials in the path of a beam of light. This instructional activity includes background information, guiding questions, directions, and a chart to record data.

Frederik is doing experiments about light to find out how it helps people to see things.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a...

Students explore color, vision, and two-point source interference. The tutorial consists of lessons and problems to check for understanding.

Acting as part of an overview on quantum theory, this section of the site answers the question, what is light? In answering the question, specific discussion is directed toward light waves and theories of light.

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

Lesson plan should be used for intermediate students. Students work in pairs or groups to create a shoe box that will bend light.

Lesson plan for various group activities about light. Provides demonstration and directions for the plans along with assessment.

In this project, you will investigate the physics of standing waves on guitar strings. You will learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you will figure out how to produce the...

An article that discusses the coupling of an electric field with a magnetic field to create electromagnetic waves. Article also discusses how different types of electromagnetic waves have different wavelengths which forms the...

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

Students learn the relevant equations for refraction (index of refraction and Snell's law) and how to use them to predict the behavior of light waves in specified scenarios.

The animation portrays a medium as a series of particles connected by springs. In this type of longitudinal wave the particles of the medium vibrate in a direction parallel to the direction of energy transport.

[Free Registration/Login may be required to access all resource tools.] The wave-particle theory and what a photon is, and evidence that electromagnetic radiation is both a particle and a wave.

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...

With this article, students can learn about and understand the concept of wave motion.

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

This article helps illustrate the behavior of electrons as waves and the uncertainty principle.
