This video provides an explanation of how the degree of magnification in a microscope is dependent on the type of microscope used. The concept of magnification is defined, and the equation for calculating magnification is introduced. Two...

A lens is a piece of transparent material, like glass, that uses refraction to form an image by changing the direction of light. There are two types of lens; converging and diverging. Converging lenses are shown using this symbol. The...

Lab Exercise 2: Microscopes and Cell Shapes

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

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

If you were alive 200 years ago you would have been given some very strange advice on how to avoid getting ill. You might have been told to carry sweet smelling flowers with you or avoid going to smelly places. This was because at that...

Now that we know a bit about the history of microscopy, let's dig into the first form that existed, light microscopy. This is the form that is familiar to most of us, as the microscopes we all looked through in high school biology class...

We Upgraded Our Microscope... Again!

Oil immersion is an interesting and complex microscopy tool.

While the microscope is one of the most exciting pieces of laboratory equipment, it is also one of the most expensive and fragile. This video illustrates how to safely and effectively use a variety of microscopes commonly found in the...

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.
