In a microscope, darkness can be observed due to the absence of light in certain areas of the specimen. This occurs when light is blocked by dense structures or when the sample is not uniformly illuminated. Additionally, contrast techniques, such as phase contrast or darkfield microscopy, enhance visibility of these dark regions by exploiting differences in light scattering or refractive indices. Consequently, the dark areas can provide valuable information about the specimen's composition and structure.
