Time for a change in perspective. A video lesson explores the progression from 2-D to 3-D images. The instructor from the physics playlist first explains the workings of a traditional camera and compares that to the creation of a 3-D...

Eyeballs or cameras—which have the best functions? The video presentations compare the important functions of the eyeball and the camera. As technology changes, cameras become more impressive, but the eyeball still out-functions the...

An episode of a film history playlist looks at camera technology and the roles of the various operators. The narrator presents an overview of different types of film camera lenses, apertures, shutter speed, frame rates, ISO, and codex....

How many ways to you know to start a fire? The video offers instructions for starting a fire without a match, lighter, or magnifying glass. As a resourceful option, it focuses on a method using a sandwich bag, water, and the sun to heat...

Tornadoes, hurricanes, whirlpools, and water going down the drain all contain of a vortex. The video demonstrates how to create two vortices that travel together the length of a swimming pool. It explains the physics behind the concept...

What should you do if you are studying for a test and your glasses break? The video introduces an easy way to instantly improve your vision. It discusses why it works and the physics behind vision, lenses, and focus.

A video explains the two most common vision problems, nearsightedness and farsightedness. It includes detail of what causes each and how they can be corrected using lenses and surgery. 

2016 was the first time viewers could watch the Olympics in virtual reality. The video discusses how diverging lenses are used to create virtual images using refracting light. It also explains how to use a ray diagram and identify the...

Did you know your eyes can only focus to within about six inches in front of them? The video explains converging lenses, refraction, images, the difference in converging and diverging, focus, focal length, and ray diagrams. 

This video covers refraction and the refractive index, which is based on density. It also explains why the angle of refraction is different than the angle of incidence and how this knowledge is helpful when it comes to lenses. 

Most people believe the equinox is the day with an equal amount of night and day, but they are wrong. The video explains what an equinox actually is, why day and night aren't equal on that day, and what an equilux is.

Take a look at the human eye through a different lens with this fun instructional video. Drawing the comparison between eyes and cameras, this resource helps young biologists better understand the anatomy and function of these...

Vision is arguably the most important of the five senses, but exactly how did we come by this amazing ability?  Find out with this engaging video on the 500 million year evolution of the human eye.

An account of the history of microscopy is given through this dissertation. An ideal assignment for life science learners to view as homework, this makes a magnifying lesson for your flipped classroom. 

Did you know a photograph can tell a story? A photojournalist tells stories with his photographs. We learn about his cameras and lenses. Watch him take photos and observe as he edits them. Say cheese! Included are links to...

In this video, Paul Andersen explains how ray diagrams for lenses can be used to determine the size and location of a refracted image. Images may be either real or virtual images. Ray diagrams for converging and diverging lenses are...

Demonstrates how concave lenses work. [3:06]

Convex lens seem confusing to you? This video lecture gives you some examples of ray diagrams for objects placed at different distances from a convex lens. [9:35]

In this video [3:25] we'll explore why regions in our scenes can go 'out of focus.' The region of our scene which is in focus call depth of field.

This video offers examples of using the thin lens equation.[12:56]

A short video investigating how to use and focus binoculars to see objects far away. [1:58]

A site dedicated to help students prepare for the AP Physics B test. This specific site reviews lights and optics including dispersion of light and the electromagnetic spectrum, reflection, refraction, mirrors, and lenses. Site contains...

Explores the relationship between the height of an object and the height of its image through a convex lens, and relates this to the ratio of their distances from the lens. [2:22]
