Final answer:
The electron microscope is the instrument used to view objects too small for the compound light microscope, using electrons rather than light to create high-resolution images.
Step-by-step explanation:
The instrument that makes it possible to see objects too small to be seen with the compound light microscope is the electron microscope. Unlike light microscopes that use light beams, electron microscopes employ a beam of electrons to produce images, offering much higher magnification and better resolving power. The preparation of the specimen for this type of microscope also kills the specimen, as it requires a vacuum for the electron beam to function effectively. There are two main types of electron microscopes:
- Scanning Electron Microscope (SEM) - creates detailed three-dimensional images.
- Transmission Electron Microscope (TEM) - allows us to view thin specimens through which electrons can pass, providing information about the inner structure.
These advanced imaging techniques have allowed scientists to observe the positions of individual atoms and track chemical reactions, significantly advancing fields such as materials science and biology.
