The Nobel Foundation provides a biography of Bragg. This site focuses primarily on his activities and accomplishments as a scientist.

Provides a long list of physics formulas for easy reference.

This page and the many pages which are indexed to focus on the behaviors of sound which characterize it as a wave. Reflection, refraction, interference, diffraction and more are clearly illustrated and explained.

This activity is designed for learners to apply their knowledge of mathematics and physics to "real life" situations. Students are presented with the situation that they are on a camping trip and wish to know the wavelength emitted by a...

The discovery of radio waves, which was widely seen as confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology, was made by German physicist Heinrich Hertz. In the...

Read about the six experiments at the Large Hadron Collider: ALICE (A Large Ion Collider Experiment), ATLAS (A Toroidal LHC ApparatuS), CMS (Compact Muon Solenoid), LHCb (Large Hadron Collider beauty), TOTEM (TOTal Elastic and...

A simulation of the Rutherford experiment. Includes an animation and an explanation of the history behind the experiment.

A collection of several pages explaining the principles which underlie Rayleigh scattering of light.

In this interactive lesson about electromagnetic waves students will explore what they can see, what they can't, and what they know about the wave nature of this thing called "light."

Here is a large collection of simple science class activities for understanding the physics of light.

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...

Instructional module focusing on light. Discussion includes historical development of particle versus wave theories and the scientific studies leading to the understanding of light waves today. Site also includes an interactive practice...

A very good introduction to the world of waves. Waves and wavelike motion, what is a wave, and categories of waves are the topics examined in this site. Many links to other wave sites.

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 article describes the race to unlock the mystery of life by determining the double helix structure of the DNA molecule. The discovery of DNA and its structure is an example of collective learning.

Provides fun activities to do involving sunlight.

A sound biography, focusing mainly on Bragg's science, what he discovered and what it's significance was. Lists many of his honors.

Why? File provides insight into four advances in telescope technology as well as shows how they are "improving our harvest of cosmic understanding."

Source of information on the subject of weather photography. There are great links, images and tips on equipment to use. For the intermediate to advanced photographer.

Identify the composition of stars by applying the ideas of quantum theory. Investigate the field of spectroscopy, and examine the spectra of stars to locate the emission and absorption lines of hydrogen.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

[Free Registration/Login may be required to access all resource tools.] Explains what causes single slit interference of light and how to find the wavelength of a single slit interference pattern using a formula.

Kids learn about the behavior of light as a wave in the science of physics including reflection, refraction, and diffraction.

[Free Registration/Login Required] This flipchart introduces fifth grade students to what sound waves do when they encounter an object. Topics covered include diffraction, reflection, absorption, and the Doppler Effect. An assessment is...
