Answer:
The apparent increase in size of an object viewed via microscopy is called magnification.
Step-by-step explanation:
Magnification in microscopy refers to the process of enlarging the apparent size of an object, making it more visible and analyzable. This optical phenomenon occurs due to the use of lenses that refract light, allowing for a detailed examination of small structures. When light passes through the objective lens of a microscope, it converges and magnifies the specimen, producing a larger image on the eyepiece.
Microscopes are equipped with various objective lenses, each offering different levels of magnification. The total magnification is determined by multiplying the magnification of the objective lens by that of the eyepiece. For instance, if the objective lens has a magnification of 40x and the eyepiece has a magnification of 10x, the total magnification is 400x. This enables scientists and researchers to observe minute details, such as cell structures, bacteria, or other microscopic entities.
