The depth of field is the part of a specimen that is in sharp focus; the depth of field decreases as the NA increases. The depth of focus on the other hand is the magnified image in focus on the film plane; depth of focus decreases as magnification increases.

You would use a microscope, specifically an electron microscope, to see the fine details of a cell's surface. Electron microscopes use beams of electrons to achieve higher magnification and resolution compared to light microscopes, allowing for detailed examination of cellular structures.

A combination of an ocular and an objective in a microscope is called an eyepiece. The eyepiece is the lens at the top of the microscope that you look through to see the specimen.
It magnifies the specimen by a certain degree to make it appear larger and let you see more detail which were not visible to the naked eye. It is done with the help of lenses which are aided in microscope
A light microscope is typically used to see the structures inside a cell, as it provides enough magnification to observe organelles like the nucleus and mitochondria. Electron microscopes can also be used for higher resolution imaging of cellular structures.
The most important aspect of a microscope is its ability to magnify and resolve details in a sample. This allows users to see objects that are not visible to the naked eye, enabling the study of microscopic structures and organisms.
The resolving power of a microscope refers to its ability to distinguish between two closely spaced objects as separate entities. It is determined by the numerical aperture of the microscope's lens and the wavelength of light used for imaging. A microscope with high resolving power can distinguish small details and produce clear images with high sharpness and contrast.

When you see a specimen clearly down a microscope, it is referred to as having a "clear or sharp focus" where the details of the specimen are in clear view. This indicates that the specimen is properly in focus under the microscope, allowing for accurate examination and observation.
The measure of clarity for an image in a microscope is typically quantified by the resolution, which refers to the ability of the microscope to distinguish between two closely spaced objects. Higher resolution means better clarity and ability to see fine details in the image. Additionally, factors such as contrast, depth of field, and focus also contribute to the overall clarity of an image in a microscope.
If you didn't have a microscope, you would not be able to view objects at a microscopic level, limiting your ability to study small organisms, cells, and details of structures. This would hinder scientific research in fields such as biology, medicine, and materials science that rely on the ability to see objects at a tiny scale.
We had to increase the magnification of the microscope in order to see the cells clearly.
A specimen is in focus when you can clearly see and distinguish its details when looking through a microscope. Adjusting the focus of the microscope allows you to bring the specimen into clearer view.
A microscope doesn't test anything. It magnifies the image of a tiny object so that one can see minute details.
The fields of microbiology and cell biology began with the invention of the microscope. The ability to study cells and microorganisms at a microscopic level revolutionized our understanding of living organisms. By allowing scientists to see previously invisible details, the microscope paved the way for advancements in these sciences.
