The image shows a compound light microscope with the following parts: - Eyepiece: This is the part of the microscope through which the user looks to see the specimen. It usually contains a lens or a combination of lenses that magnify the image. In the image, the eyepiece is located at the top of the microscope. - Arm: This is the part that connects the base and the body tube of the microscope. It provides support and stability to the microscope. In the image, the arm is the horizontal piece connecting the base and the body tube. - Body tube: This is the part of the microscope that contains the objective lenses and connects the eyepiece to the stage. In the image, the body tube is the long, cylindrical piece between the arm and the stage. - Objective lenses: These are the lenses that are closest to the specimen and provide the initial magnification. In the image, there are three objective lenses located at the bottom of the body tube. - Stage: This is the platform where the specimen is placed for observation. It usually has a mechanism for moving the specimen in the x-y plane. In the image, the stage is the flat, circular piece between the body tube and the base. - Coarse focus knob: This is the knob that is used to make large adjustments to the focus of the microscope. It is usually located on the right side of the microscope. In the image, the coarse focus knob is the larger knob on the right side of the base. - Fine focus knob: This is the knob that is used to make small adjustments to the focus of the microscope. It is usually located near the coarse focus knob. In the image, the fine focus knob is the smaller knob on the right side of the base. - Diaphragm: This is the part that controls the amount of light that enters the microscope. It is usually located below the stage. In the image, the diaphragm is the circular piece with a hole in the center located below the stage. - Light source: This is the part that provides the light that illuminates the specimen. It is usually located at the bottom of the microscope. In the image, the light source is the rectangular piece at the bottom of the base.
