What are the three tasks that a microscope must accomplish?
What are the three tasks that a microscope must accomplish?
produce a magnified image of the specimen (magnification), separate the details in the image (resolution), and render the details visible to the eye, camera, or other imaging device (contrast)
What is the difference between a simple microscope and a compound microscope?
What is the difference between a simple microscope and a compound microscope?
A simple microscope uses just one lens for magnification, while a compound microscope uses two optical parts (ocular lens and objective lens) for magnification

Study Notes
Microscope Tasks
- A microscope must accomplish three tasks: magnification, resolution, and illumination of the specimen
Types of Microscopes
- A simple microscope consists of a single lens, whereas a compound microscope consists of multiple lenses
- A compound microscope provides greater magnification and resolution than a simple microscope
Magnification and Specimens
- A compound microscope can provide a maximum magnification of up to 1000-1500 times
- Compound microscopes are commonly used to observe microorganisms, cells, and small tissues in biology
Electron Microscopes
- The purpose of electron microscopes is to provide higher magnification and resolution than compound microscopes
- Electron microscopes use a beam of electrons instead of light to produce an image of the specimen
