Serena measured the image of one of the bacterial cells to be 32 mm. If the magnification of the image is 8,000X, what is the actual size of the bacterial cell?
4 μm
0.004 μm
256,000 μm
0.25 μm
What steps should Burt use follow to calculate the actual size of each bacterial cell?
Step 1: Calculate the magnification by measuring the scale bar image ÷ actual size
Step 2: Measure image of bacterial cell ÷ magnification
Step 1: Calculate the magnification by measuring the scale bar image x actual size
Step 2: Measure image of bacterial cell ÷ magnification
Step 1: Measure the image of the bacterial cell
Step 2: Divide the image size by the scale bar size
He can't, it is impossible to calculate
Which is the correct equation to calculate image size -
Image size = magnification / actual size
Image size = magnification x actual size
Image size = actual size / magnification
Image size = actual size x magnification
Which is the correct equation for magnification -
Magnification = actual size / image size
Magnification = actual size x image size
Magnification = image size / actual size
Magnification = image size x actual size
What is the correct equation to calculate actual size?
Actual size = Image size / magnification
Actual size = Image size x magnification
Actual size = magnification / Image size
Actual size = magnification x Image size
= 1 mm?
Eyepiece = 10X
Objective lens = 55X
A microscope has a magnification of 10X. A cell appears to be 550 um in length. How long is the actual cell
550 um
100 um
50 um
55 um
