FLASHCARD QUESTION

Front

What is the formula to calculate the field of view under different magnifications?

Back

Field of View (Low Power) x (Low Power Magnification / High Power Magnification) = Field of View (High Power)

FLASHCARD QUESTION

Front

What is the actual size of an object if its image measures 450 mm at a magnification of 15,000x?

Back

Actual Size = Image Size / Magnification = 450 mm / 15,000 = 30 µm

FLASHCARD QUESTION

Front

If each division on a microscope scale represents 100 µm, how long is an organism that measures 4 divisions?

Back

Length of organism = 4 divisions x 100 µm/division = 400 µm.
