Magnification Flashcards
What is the formula to find magnification?
Magnification= image size / real size
What is the formula to find total magnification?
Total magnification= eyepiece lens magnification x objective lens magnification
What does resolution mean?
How well a microscope distinguishes between two points that are close together.
What does a higher resolution mean?
The image can be seen more clearly and in more detail
When were light microscopes invented?
1950s
How do light microscopes work?
They work by passing light through the specimen. They let us see things like nuclei and chloroplasts and we can also use them to study living cells
When were electron microscopes invented
1930s
How do electron microscopes work?
They use electrons. They have higher magnification and resolution than light microscopes.
They let us see much smaller things in detail
Allows greater understanding of how cells work and sub cellular structure
