Detailed explanation-1: -Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through. The eyepiece lens typically magnifies an object to appear ten times its actual size, while the magnification of the objective lens can vary.

Detailed explanation-2: -Compound Microscopes Typically, a compound microscope is used for viewing samples at high magnification (40-1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).

Detailed explanation-3: -Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively.

Detailed explanation-4: -Parts of a Microscope It consists of mainly three parts: Mechanical part-base, c-shaped arm and stage. Magnifying part-objective lens and ocular lens. Illuminating part-sub stage condenser, iris diaphragm, light source.

Detailed explanation-5: -Objective lenses are the lenses that directly observe the object the microscope user is examining. In stationary microscopes, the objective lens then focuses reflected light from the object up a tube toward the ocular lens, which is the lens the user looks through.
