If an image measured 3.5 mm and the magnification was x 1, 000, how big would the actual object be?
A
0.0035 mm
B
0.035 mm
C
3500 mm
D
0.35 mm
Explanation: 

Detailed explanation-1: -Magnification = image size / actual size. Actual size = image size / magnification. Image size = magnification x actual size.

Detailed explanation-2: -Magnification equation Magnification = image size / actual size. Actual size = image size / magnification.

Detailed explanation-3: -Estimating the Size of the Specimen Under Observation Remember that 1 m = 0.001 mm. To estimate the size of an object seen with a microscope, first estimate what fraction of the diameter of the field of vision that the object occupies. Then multiply the diameter you calculated in micrometers by that fraction.

Detailed explanation-4: -You will have to multiply the eyepiece magnification by the objective magnification to find the total magnification before dividing the field number. For instance, if your eyepiece reads 10X/22, and the magnification of your objective lens is 40. First, multiply 10 and 40 to get 400.
