Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

This introductory, algebra-based, two-semester college physics book is grounded with real-world examples, illustrations, and explanations to help students grasp key, fundamental physics concepts. This online, fully editable and customizable title includes learning objectives, concept questions, links to labs and simulations, and ample practice opportunities to solve traditional physics application problems.

In this activity, students construct their own pinhole camera to observe the behavior of light.

This webpage from National Aeronautics and Space Administration (NASA) provides an astronautå�è÷€�åÜ€�_s photograph of the moon viewed from the top of the atmosphere. The appearance of the nearly translucent moon is described in regards to optics, and an introduction to NASAå�è÷€�åÜ€�_s observations of the top of the atmosphere is provided. The site also contains links to numerous new images from the Earth Observatory.

This manual provides simple demonstrations to show how lenses and mirrors are used to create telescopes. It was created for use by the Night Sky Network of astronomy clubs.

Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output.

An online simulation for seeing how colour and the mixing of colour looks like on a stage and on the actors.

The following resource contains the assets (or resources) to accompany the Sask DLC Science 8 course. Please note that this is not the content of the course, but the assets used to support and deliver it. The files are organized in a zip folder and a collection. 

Explore an active area of research in optical physics: producing designer pulse shapes to achieve specific purposes, such as breaking apart a molecule. Carefully create the perfect shaped pulse to break apart a molecule by individually manipulating the colors of light that make up a pulse.

Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?

In this lesson, students learn that light travels in a straight line from a light source and that ray diagrams help us understand how an image will be created by a lens. In the accompanying activity, students explore the concepts behind the workings of a pinhole camera.

This page from NASA's Earth Observatory shows images of visible tracks made in the Earth's atmosphere from clouds forming around ship exhaust particles. One of these images shows the relative sizes of the particles, and the text relates the relative sizes to the relative brightness of the clouds that are formed.

Students are provided with an understanding of sound and light waves through a "sunken treasure" theme a continuous storyline throughout the lessons. In the first five lessons, students learn about sound, and in the rest of the lessons, they explore light concepts. To begin, students are introduced to the concepts of longitudinal and transverse waves. Then they learn about wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, they learn all about echolocation what it is and how engineers use it to "see" things in the dark or deep underwater. The last of the five sound lessons introduces acoustics; students learn how different materials reflect and absorb sound.

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr. Gehrels explains different methods for detecting and imaging high-energy particles, how they work, and the advantages and disadvantages of each, using examples and imagery from NASA missions.
