Why is it that with a standard transmission electron microscope, resolution is actually about two orders of magnitude less than its theoretical limit?
A)The lenses of an electron microscope exhibit serious spherical aberration problems, which can be avoided by using a very small N. A.
B)The lenses of an electron microscope exhibit serious spherical aberration problems, which can be avoided by using a very large N. A.
C)If electron wavelength is too high, spherical aberration distorts the image.
D)If electron wavelength is too low, spherical aberration distorts the image.

Question

Quizplus · Accepted Answer

The lenses of an electron microscope suffer from significant spherical aberration issues, which limit the resolution far below the theoretical limit. This aberration distorts the image, making it difficult to achieve the maximum possible resolution.
