3. Wet mount What is a wet mount?
What happens if cover slip is not on correctly?
Why does specimen have to be thin?
A wet mount is a slide with a specimen in water
You will get air bubbles and not be able to see
So light can shine through it

4. Magnification How do you calculate magnification?
If the objective lens is 40 and the ocular lens is 10, what is the magnification?
If the magnification is larger, do you see more or less of the object?
Objective lens power x ocular lens power
40 x 10 = 400
You see less

5. How images move
How do images appear, compared with their normal view? (think of letter e)
If you want image to move up, how do you move slide?
If you want image to move left, how do you move the slide?
Upside down and backward
Down
Right
