A microscope is an optical instrument that magnifies small objects, allowing us to see details that are not visible to the naked eye. It uses lenses to focus light and create a magnified image of the specimen being observed. There are various types of microscopes, including light microscopes, which use visible light, and electron microscopes, which use beams of electrons for higher magnification. Microscopes are essential tools in many fields, including biology, medicine, and materials science. They help scientists study cells, bacteria, and other tiny structures, contributing to advancements in research and technology. By providing a closer look at the microscopic world, microscopes enhance our understanding of life and materials.
