Q

Ex. Magnifying glass
3

Light passes through specimen then through two or more lenses.
4
Q
Why do we stain specimens?
A
Cells originally appear colourless, staining it helps to spot the different organelles
5
Q
What is the formula to figure out total magnification?
A
Ocular lens x objective lens = total magnification
6
Q
What is the formula to calculate the field of view of another lens?
A
Total magnification (1) x field of view (1) = total magnification (2) x field of view (2)
How to solve:
Total magnification (1) / total magnification (2) = y
Y x field of view (1) = field of view (2)
