Detailed explanation-1: -The correct answer is a Fine adjustment knob.
Detailed explanation-2: -Fine Adjustment Knob-This knob is inside the coarse adjustment knob and is used to bring the specimen into sharp focus under low power and is used for all focusing when using high power lenses.
Detailed explanation-3: -The fine adjustment knob must only be used using a high power objective lens because the distance between the lens and the specimen slide is very short due to the larger size of the high power objective lens. The fine adjustment knob draws the lens closer to the specimen at only small distances.
Detailed explanation-4: -The fine focus know can be used with all objectives, including the 4x, but the effect will not be visible with this latter one (you will have to turn the knob many times, which is inconvenient).
Detailed explanation-5: -5. FINE ADJUSTMENT KNOB-A slow but precise control used to fine focus the image when viewing at the higher magnifications.
