Magnification can be calculated using the equation: magnification = size of image / actual size of the specimen. A bacterial cell is 0.003mm long. A magnified image of the cell is 21mm long. The magnification of the image is ×_____.
Question
Magnification can be calculated using the equation: magnification = size of image / actual size of the specimen. A bacterial cell is 0.003mm long. A magnified image of the cell is 21mm long. The magnification of the image is ×_____.
Solution
To calculate the magnification, we need to divide the size of the image by the actual size of the specimen.
Given: Size of image = 21mm Actual size of specimen = 0.003mm
So, Magnification = Size of image / Actual size of specimen = 21mm / 0.003mm = 7000
Therefore, the magnification of the image is ×7000.
