In this experiment, you will measure the speed of light using a microwave oven, some egg white, and a ruler. This short project proves to be an extremely interesting choice for a science lab, with pictures for illustration, and thorough...

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again. Outfit yourself with a simple handheld laser pointer, a protractor, and Jell-O, and you're ready to get started.

This resource provides a concise overview of the speed of light and the Ole Roemer, the first man to measure it.

Using an interesting and intriguing format, this page discusses the question of "How does one measure the speed of light." Explanation focuses on Galileo's and Roemer's efforts to obtain a reasonable value. Also discusses Heinrich...

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.

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.

An interactive timeline that students can read, watch and listen to in order to understand the scientist who tried and succeeded in measuring the speed of light.

How fast does light travel? How does its speed change when it travels through different media? Learn how scientists calculate the speed of light and some interesting facts.

If the speed of light remains a constant then time and distance change. Oh, it can be confusing! This text will help clear up the confusion. Discussion questions should serve to reinforce comprehension.and exercises

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will calculate the wavelength, frequency, and energy of light using Planck's constant and the speed of light. They will...

A good mathematical account of what happens to time as you approach c: the speed of light. Also provides a rather a fascinating video (fly through the Lattice) - don't miss it. Take some time and explore this site.

This page is a continuation of a tutorial about light reflection and refraction. It contains a diagram and suggestions on how to derive Snell's Law, which governs the refraction of light in a medium. For background to this derivation,...

A detailed discussion of the nature of light, how it can travel through a vacuum, and how the speed of light is affected when light travels through a medium.

Addressed with questions about relative speed and the speed of light, students begin to "think like Einstein" while exploring the science behind the mystery of time travel.

Practice Space Math! Math is the cornerstone of space travel. Familiarize yourself with all the ways math can help you study the solar system. Practice math problems in areas such as speed of light, the distance of planets to the sun,...

In this interactive physics tutorial about refraction, students investigate the topic of the direction of bending of a light wave.

A series of short descriptions of possible physics demonstrations for illustrating or measuring the speed of light. Suitable as a supplement to a teacher lesson plan or as an idea-generator for student projects.

Describes research into whether neutrinos travel faster than the speed of light.

Try out your ability to think like Einstein by working through two thought experiments that help explain how satellites stay in orbit and how the speed of light affects the universe.

For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning...

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.

This site from Stanford University is on the topic of simultaneity in relativity.

A tutorial page explaining how the speed of light is dependent upon the optical density of the material through which it moves. Optical density is related to the index of refraction; sample values are given.

In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light. [4:50]
