Verified step by step guidance1
Understand the purpose of microscopy: Microscopy is used to observe objects or specimens that are too small to be seen clearly with the naked eye. The primary goal is to magnify and resolve details of the specimen.
Learn the role of lenses in a microscope: Lenses are optical components that bend light rays through refraction. This bending focuses the light to magnify the image of the specimen.
Recognize the types of lenses in a microscope: Microscopes typically have two main types of lenses—objective lenses (close to the specimen) and ocular lenses (eyepiece). The objective lens provides the initial magnification, while the ocular lens further magnifies the image.
Clarify why other options are incorrect: The source of illumination is provided by a light source, not the lenses. Staining is a separate process to enhance contrast, and temperature regulation is not a function of the lenses.
Conclude the primary role of lenses: The lenses in a microscope are specifically designed to magnify the image of the specimen being observed, allowing for detailed examination.
