Question

Quizplus · Accepted Answer

Brightfield microscopy involves illuminating the specimen with white light, allowing the observer to view the specimen against a bright background. This is the most basic form of microscopy where light is transmitted from a source below and through the microscope slide. Other options involve techniques used in different types of microscopy, such as electron microscopy (B) and fluorescence microscopy (C), but not brightfield microscopy.
