Detailed explanation-1: -Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage.
Detailed explanation-2: -IRIS DIAPHRAGM CONTROL-A lever (or rotating disk) that adjusts the amount of light illuminating the slide.
Detailed explanation-3: -Iris: The iris is the colored part of the eye that surrounds the pupil. It regulates the amount of light that enters the eye.
Detailed explanation-4: -The size of the field diaphragm is controlled by rotating a knurled ring which is concentric with it. The field diaphragm controls the area of illumination. Locate the field diaphragm and its knurled ring. The magnification of an image is primarily controlled by the objectives which are housed in a rotating nose piece.
Detailed explanation-5: -Answer and Explanation: The amount of light entering a microscope may be adjusted by regulating the diaphragm, therefore the answer is b. The diaphragm, also called the iris diaphragm, adjusts the size and intensity of the cone of light that reaches the specimen.
