B1.1 the world of the miscroscope Flashcards
1
Q
How do you calculate magnification
A
Actual (real) size= image size/ magnification
2
Q
how do we measure the size of cells in order biggest to smallest
A
millimetres (mm)
micrometer (qm)
nanometers (nm)
1mm=1000qm
1qm=1000nm
3
Q
what is magnification
A
how many times bigger the image is than the real size of the specimen you are looking at
4
Q
what is resolution
A
how detailed an image is
5
Q
Qualities of a light microscope (3)
A
Uses light
lower magnification 
lower resolution
6
Q
qualities of electron microscopes (3)
A
uses electrons
higher magnification
higher resolution
7
Q
what does this mean in comparison of electron and light microscopes
A
electron microscopes can be used to study cells in much better detail and show smaller organelles
