'Animalcules'
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
Objects appear magnified and clearer when viewed through a light microscope due to the lenses that focus light to create an enlarged image. The microscope allows for detailed examination of the specimen's structure and features not visible to the naked eye. The use of specialized stains or dyes can enhance contrast and visibility of specific parts of the object being observed.

When viewed through a microscope, things appear to move in the opposite direction than they are really moving. If you move an object to the right, it appears to move left. The lenses of the microscope reverse the image.
The working distance of a stereo microscope refers to the distance between the objective lens and the specimen. A longer working distance allows for larger objects to be viewed, as there is more space between the lens and the specimen. Conversely, a shorter working distance limits the size of objects that can be viewed due to the physical constraints of the microscope's design.
Things that are too small for a light microscope, such as viruses and molecules, can be viewed using an electron microscope. Electron microscopes use a beam of electrons instead of light to magnify objects at a much higher resolution than light microscopes.
Opaque objects do not let light pass through them, so they block the light needed for the microscope to form an image. This prevents the microscope from capturing a clear image of the object. As a result, opaque objects appear dark and featureless when viewed under a light microscope.
Objects that are viewed through a microscope are typically placed on a glass slide, which provides a flat and stable surface for the object to be observed. The slide is usually covered with a thin glass coverslip to protect the specimen and hold it in place while allowing light to pass through for magnification.
Objects appear larger and more detailed in a microscope due to magnification of the image. Light passing through the object is refracted and focused by lenses in the microscope, allowing for increased resolution and visibility of fine details. Magnification and resolution together contribute to the enhanced clarity of the object's features when viewed under a microscope.
