Site provides a diagram as well as a scientific explanation of light reflection. Includes links to ray optics, light and physics.

Physicist as a career is a very broad spectrum. This site from Science Buddies relates the general requirements and education needed to be a physicist and lists the many sub-fields in which physicists can specialize. Included is a video...

A collection of video lectures from a physics course focusing on vibration and waves taught at the Massachusetts Institute of Technology. The course overviews topics dealing with mechanical vibration and waves with twenty-three lectures....

This site from Georgia State University discusses the means by which mirrors and lenses are combined to produce an optical instrument which accomplishes a specific purpose. Good illustrations.

A discussion from Georgia State University of different types of mirrors and the images which they create. Discusses different instruments which use mirrors to produce images.

Students use this tutorial to investigate the refractive ability of converging and diverging lenses.

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

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

An extensive introduction to the career of optician, with information on the nature of the work, working conditions, employment qualifications, job outlook, and earnings.

This biographical note on Wilhelm Conrad Rontgen describes his boyhood, upbringing, education, scientific work and accomplishments. Focuses on his studies of Xrays.

For elementary students, this would be a great demonstration on properties of light and optics. For middle school and high school, this would be a great start to a lab but needs experimentation. Site by Exploratorium.

Several short descriptions and graphics of demonstrations which illustrate principles of interference. Suitable as a supplement for a teacher lesson plan or as an idea-generator for a student project.

Ray diagrams are useful tools for determining the location of an image as produced by a concave mirror. All concave and convex mirror ray diagrams can be constructed from knowledge of the behavior of two rays. Learn here about ray diagrams.

Ray diagrams are useful tools for determining the location of an image as produced by a concave mirror. Of all the rays which emanate from the top of the object arrow and are incident to the mirror, there are two rays whose behavior at...

An experiment using a water lens that demonstrates how the eye sees an image. Accompanied by an explanation of what's happening, and a link to an article on refraction.

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

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...

Explains what polystyrene is and its many different properties and uses.

This article from Khan Academy provides information about mirrors. This information is intended for the Class 12 Physics Course (India).

Have you ever wondered why some people need glasses and others don't? It's because of the way light is focused by the lens in your eye. This lens, like magnifying glasses, eyeglasses, and contact lenses, is considered a thin lens.

Short descriptions and graphics of three demonstrations which illustrate the diffraction phenomenon. Suitable as a supplement for a teacher lesson plan or as an idea-generator for a student project.

Short descriptions of possible physics demonstrations for illustrating dichroic polarization and the role of Polaroid filters in blocking roadway glare. Suitable as an idea-generator for student projects.
