LAB 1 PRACTICE QUESTIONS
1
The microscope you are using has a field diameter of 400  m when using the 40x objective. A cell which fills 50% of the field of view at 40x would be
________ in diameter.

LAB 1 PRACTICE QUESTIONS
The Microscope View

LAB 1 PRACTICE QUESTIONS
What You Know
50%
400  m = 0.4 mm

LAB 1 PRACTICE QUESTIONS
The Final Step
50%
50 % X 400  m =
400  m = 0.4 mm

LAB 1 PRACTICE QUESTIONS
The Answer
50%
50 % X 400  m =
200  m or
0.2 mm
400  m = 0.4 mm

1 kilometre (1km) = 1000 metres
1 metre (1m) = 1000 millimetres
1 millimetre (1mm) = 1000 micrometre micrometre (1  m) = 1000 nanometre (nm)

LAB 1 METRIC LENGTH REVIEW
 The exception to the 1000 rule for distance conversions is cm’s
 1 metre is equal to 100 cm and 1 cm is equal to 10 mm
 1 cm = 10 mm
