The 40x objective is often avoided when examining stained preparations because it typically provides a narrower field of view and less depth of field, making it challenging to focus on the entire specimen. Additionally, stained samples can have varying thicknesses, and higher magnification can result in difficulty in achieving clear images of the overall structure. Instead, lower magnifications like 10x or 20x are preferred for a more comprehensive overview before switching to higher magnifications for detailed examination.
That is not the case; you are looking at how some dissection specimens have had their veins and arteries stained. It is the dyes used in the preparation of the specimens.
Counterstaining means to apply a second stain to a preparation for microscopy. Counterstaining is used to stain in a contrasting way those parts of the preparation that have not been stained by the first stain.
You typically need less light when viewing a stained preparation, as the stains used absorb or reflect light in specific ways that enhance contrast and visibility of cellular structures. Adjusting the light source to a lower intensity can help improve the clarity of the stained specimen.
