Final answer:
The eyepiece or ocular lens of the microscope takes the real image from the objective lens and magnifies it into a larger virtual image that is easy to view.
Step-by-step explanation:
The part of the microscope that uses the real image created by the objective lens and forms an enlarged virtual image is the eyepiece or ocular lens.
The eyepiece acts as a magnifying glass for the intermediate image produced by the objective lens, further magnifying it within its focal length, which results in a much larger virtual image that is easier for the eye to view. This process of magnification is the basis for the high degree of detail that can be observed using a compound microscope.
