Frequently Asked Questions

What is a microscope and how does it work?

  • A microscope is a scientific instrument that allows us to observe objects that are too small to be seen with the naked eye.
  • It uses a combination of lenses to magnify a specimen, making it appear larger and clearer.

There are two main types of microscopes:

1. Light microscope: This microscope uses visible light to illuminate the specimen. It is the most commonly used type of microscope and allows us to see things such as cells and bacteria.

2. Electron microscope: This microscope uses a beam of electrons to magnify the specimen. It provides a much higher magnification than a light microscope and is used to study the smallest details of objects like viruses and molecules.

Regardless of the type, all microscopes work on the principle of magnification. The lenses in the microscope magnify the specimen, making it look larger than it actually is.

The sample is placed on a slide and illuminated by a light source. The objective lens, located at the bottom of the microscope, gathers light from the sample and magnifies it. This magnified image then passes through the eyepiece lens, which further magnifies the image for viewing by the observer.

Microscopes have been crucial to scientific discovery because they have allowed us to see and study things that were previously unknown. From discovering microscopic organisms to studying the structure of molecules, microscopes have opened up new realms of scientific inquiry and revolutionized our understanding of the world around us.
