3. Match the microscope part with its function: Allows the observer to move the slide across the stage either forward or backwards or laterally. Moves the stage (or body tube) up or down small distances. Allows detailed clarity of the specimen. Provides illumination of the specimen. Located beneath the condenser and iris diaphragm. Lens found beneath the stage that concentrates light before it passes through the specimen to be viewed. A turning device that holds the objectives. Located on the revolving nosepiece-- several different levels of magnification are available when each clicked into place

1. Place the following steps of using a light microscope in order to focus on a specimen: -With the stage in the highest position, turn the course adjustment knob slowly to focus on your specimen. -Put the scanning (4x) objective lens into position. -Turn the course adjustment knob so that the stage is moved as high as it will go. -Use the stage control knobs to center the specimen so that it is directly over the light coming from the bottom of the stage. -Turn on the light microscope and adjust the light intensity. 2. The property of the light microscope known as resolution can best be described as The ability to change objective lenses while maintaining relative focus on your specimen. The ability to differentiate small details seen on your specimen. The combined magnification power of the objective lens times the power of the ocular lens. The ability of light to bend as it passes through two substances that have different refractive indexes.
