The objective lens of a compound microscope has a numerical aperture of 0.4. The maximum useful magnification of the microscope is:
400x
1,000x
10x
There is not enough information given to calculate this
the correct answer is not given
To find the maximum useful magnification of a microscope, you need to use the formula:
Maximum Useful Magnification = Numerical Aperture × 500
In this case, the numerical aperture is given as 0.4. Plugging this value into the formula:
Maximum Useful Magnification = 0.4 × 500 = 200
Therefore, the maximum useful magnification of the microscope is 200x.
