Most student microscopes are classified as light microscopes. In a light microscope, visible light passes through the specimen (the biological sample you are looking at) and is bent through the lens system, …

Scientists use light microscopes to study cell structures and to observe cell movements and interactions. For example, light microscopes can be used to observe cell division, the behavior of microorganisms, …

In order to view cells, scientists must use magnifying tools called microscopes. Simple light microscopes, such as magnifying glasses, generally are not powerful enough to view cells. …

We're going to pretend that we're the scientists or pathologists looking underneath a microscope to see these bacteria. So here's something that they might be looking at, and you can see that there are five …

Let's explore how a magnifying glass (simple microscope) really works. Created by Mahesh Shenoy.

Light, as electromagnetic waves, can oscillate in specific directions. This phenomenon is called polarization. Explore into the difference between polarized and non-polarized light, and see how …

we have a compound microscope whose objective focal length is 5 millimeters eyepiece focal length is 2 and 1/2 centimeters a sample is kept at 6 millimeters from the objective find the magnifying power of …

What is refraction and why does it happen? Why does light bend when being changed into one median to another? And where can we observe refraction the most?

Let's explore the principle of a compound microscope and then logically build one, step by step. Created by Mahesh Shenoy.
