Final answer:
This question involves calculating the total magnification of microscope lenses in Biology by multiplying individual lens magnifications, crucial for understanding the scale of microscopic observation.
Step-by-step explanation:
The subject of this question is related to the use of microscopes in Biology, specifically regarding the calculation of magnification. For each lens on a microscope with its magnifying power engraved as a number followed by 'X', one can find individual magnifications and then calculate the total magnification by multiplying the individual magnifications together. This calculation is essential in understanding how much an image has been magnified when viewing through a microscope lens.
For example, if a micrograph is recorded at 40× magnification and the image is magnified an additional 2×, the final magnification will be 80×, which is computed by multiplying the original magnification by the additional factor. Such a calculation helps in better understanding the scale at which one is observing microscopic structures or organisms.
Please take into account that the variation in magnification can occur when micrographs are viewed electronically, as the screen size and magnification of the electronic device can affect perceived size.
