Refraction by Lenses
The Refraction by Lenses Video Tutorial explains the difference between a converging and diverging lens in terms of their shape and the manner in which they refract light. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
- How can a lens be described?
- In what manner does a converging and a diverging lens refract light?

Additional and Related Learning Tools
Minds On Physics, Refraction and Lenses Module, Mission RL7
Student persistence with Minds On Physics combined with reflective thinking and the use of our Help function will put any student at the top of the class. This mission pertains to the difference between converging and diverging lenses. It's a perfect follow-up activity.
Physics Interactive, Refraction and Lenses Chapter, Optics Bench Simulation
Sometimes you learn best by playing. And our simulations allow you to do just that. Our Optics Bench simulation allows you to move an object to varying locations in front of a lens (converging or diverging), view the light rays, and observe the image location and characteristics. Play with the simulation, learn, and then follow it up with a Concept Checker on the same topic

Teacher Resources
Curriculum Corner, Refraction and Lenses
Our Curriculum Corner section of the website includes a large collection of Think Sheets that make great complements to the video. Each Think Sheet focuses on a single concept and is structured to incrementally guide a student through the concept. They make for great follow-ups to the video, good cooperative group activities, and inclusions in any lesson plan. And if you need source documents (Microsoft Words), extended licensing rights, and solutions, consider the purchase of our low-cost Solutions Guide download. Here's a Think Sheet that provides a great fit to the video:
