Comparing Light and Electron Microscopes

This video tutorial explains the differences between light and electron microscopes. Light microscopes are small, easy to use, and affordable, but have limited resolution due to their reliance on light. Electron microscopes, while large and expensive, offer much higher resolution by using electrons, allowing for detailed study of sub-cellular structures. The video highlights the pros and cons of each type and provides resources for further learning.
