Refraction Set: 3. This clip looks at the role of refraction in animals. Examples include the lenses of the eye and structural coloration.

This video explains the concepts of myopia and hyperopia and how they can be corrected using concave and convex lenses. It also provides a simulation tool to help students understand the focal length, position, nature, and size of images...

It explains two types of spherical lenses; convex and concave lenses. It also explains technical terms related to them.It also describes the converging property of convex lens and diverging property of concave lens.

It expresses the lens maker formula and lens formula,explains refraction by lens,power of lens,combination of thin lenses in contact.

Lab Exercise 2: Microscopes and Cell Shapes

It about the optical devices-the eye, telescope, image beyond 2F length, image at infinity and telescope.

Our prejudices are often outdated and unecessary. Putting these lenses down can be liberating...

It describes sign convention for spherical lenses, lens formula and its application, magnification and power of a lens.

BONUS VIDEO The Microcosmos Microscope

This video is an educational lecture that explains the properties of concave lenses, how they form images, and the type of images they create. The video describes the definition of a lens and how it refracts light as it crosses the...

The world's largest digital camera is currently being assembled at a warehouse in California. We caught the short window of time to see the camera's massive lens.

This video provides a basic understanding of lenses, explaining how they work to focus light and form images. It covers the different types of lenses, their uses in various devices, and even highlights how our own eyes function as...

The video is a lecture on convex lenses, explaining the way they work to bend and focus light. The speaker defines what a lens is, describes how convex lenses function, explains how to construct a ray diagram with a convex lens, and...

A diverging lens is sort of like the opposite of a converging lens because it curves inwards instead of outwards. It is represented with this symbol, interesting I know. Diverging lenses refract the light in a way, which makes them...

Through live action footage and animated diagrams students will come to understand that refraction is the bending of light rays when they go from one medium to another medium of different density. The program explains why light refracts...

This video provides an overview of the element germanium. It describes the physical properties of germanium and its discovery by Clemens Winkler. The video also discusses the various uses of germanium, such as in semiconductors, optical...

This video examines the various uses of light and the role of different types of lenses in light refraction. The way in which eyeglasses, contact lenses, and binoculars manipulate light to allow us to see better is illustrated. Other...

Using animation and real world examples, this video explores the change in kinetic energy of particles with heating and cooling that produces expansion and contraction and change in density in matter. Students will observe and come to...

Upon viewing the Light video series, students will be able to do the following: List some of the reasons light is important to all living things. Understand that light is a type of energy. Describe how light behaves both as a wave and...

What is the difference between making cubes for optical fibers and eye glass lens? What is multiplexing? Magical Glass Technology, Part 3

We Upgraded Our Microscope... Again!

Through animation, I explain various aspects of focal length, from the principle of the subject, to crop factor, and finally the different classifications of lenses.

In this animation, I explain Aperture and how it interacts with the various parameters of photography.

Students will learn about the discovery of cells, the development of the cell theory, and the differences between animal cells and plant cells, Animations illustrate the different parts of a cell. Other terminology includes: organelles,...
