The Physics Classroom:refraction/ray Model of Light: Optical Density/light Speed

Focusing on the question, "By how much does light refract when it crosses a boundary?" this physics tutorial will allow students the opportunity to explore these concepts of refraction.

Through illustrated examples and animated tutorials, students discover what causes refraction.

Through illustrated examples and interactive practice problems, students explore the details of Snell's Law.

Using the Lens Equation and the Magnification Equations, students determine numerical information about image distance and image size.

Students learn how the Archer fish can reach out of the water and catch its prey with pinpoint accuracy, despite the physics that causes refraction of light.

Through illustrated examples, students explore the physics phenomenon of total internal reflection when light travels through several medium boundaries.

Students take an in-depth look at the physics behind image formation.

Students discover the four parts of the eye are the most instrumental in the task of producing images that are discernible by the brain.

An introduction to the human eye as it relates to the physics ray model of light and image formation.

A brief introduction to the physics side of farsightedness, and how lenses correct this vision defect.
