The concepts of refraction and reflection gel with your physical science class during this colorful exploration. Shining lasers through Petri-dish-shaped gelatin desserts, they will notice how the light travels and bounces off the sides....

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Nineteen word problems dealing with frequency, speed, reflection, and refraction of light are provided here. Empower your physics masters to manipulate equations for computing angles, focal lengths, image heights, and more! This is a...

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

The University of Hawaii has published a vast collection of midterm and final exams for their Physics 152 course. This particular exam offers a variety of assessment methods, and covers the topic of electromagnetic radiation....

Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

True-false and multiple-choice questions are posed in Part A of this exam, covering the topic of electromagnetic radiation. In Part B, problems relating to refraction must be solved. This is a well-rounded exam that will help you...

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...

Students measure angles of refraction as the light travels through gelatin.  In this experimental lesson students complete a refraction lab and plot their data.

Students investigate refraction and reflection of light. In this light lesson, students perform 3 activities to observe light interacting with matter by using a flashlight. They explore refraction using a glass of water and reflection...

In this refraction activity, students will explore the property of light called refraction. Students will conduct a quick experiment to understand how light is refracted. Then students will complete 2 short answer questions.

In this refraction worksheet, students perform an experiment by putting a penny in a bowl, walking off and turning back around to see if they can still see the penny or not.

Students define and discus the concepts of wave fronts and rays. In groups, they distinguish between specular and diffuse reflections and use Snell's Law to predict the path of light rays. They calculate the speed of light through...

This lesson engages students in learning about light through multiple sources. Students will learn how light is produced, reflected, refracted, and separated. Students will communicate their findings through an independent project that...

This lesson contains the following labs: Rainbows, Refraction with Prisms, and What Color Is It? Students will study light by reading various nonfiction texts and viewing a video lesson. Then students will engage in the following labs:...

This lesson engages students in learning about light. Studets will describe how light is produced, reflected, refracted, and separated.

Glass objects seem to disappear when placed in cooking oil.

A discussion of refraction and its application to sound waves. Using analogies, graphics and real-life applications, this page and those that accompany it explain why and when sound waves bend.

Chinese-language Java applet illustrating Fermat's principle that light follows the fastest path between any two points. Excellent animation and accompanying text. Relates Fermat's principle to Snell's law.
