What is the name of the part of the microscope that you turn to make the image clearer?
A
focussing lens
B
focussing wheel
C
eyepiece lens
D
objective lens
Explanation: 

Detailed explanation-1: -Use the focus knob (4) to place the sample into focus and readjust the condenser (7) and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).

Detailed explanation-2: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with in-stage condenser lenses render a sharper image than those with no lens (at 400x).

Detailed explanation-3: -NOSEPIECE-A circular plate with 4 objective lenses that can be rotated into position for different magnifications. 10. OBJECTIVE LENS-Four separate lenses that magnify the image (4X, 10X, 40X and 100X) depending on the objective in use.

Detailed explanation-4: -It is through the microscope’s lenses that the image of an object can be magnified and observed in detail. A simple light microscope manipulates how light enters the eye using a convex lens, where both sides of the lens are curved outwards.

Detailed explanation-5: -Focus (coarse), The coarse focus knob is used to bring the specimen into approximate or near focus. Focus (fine), Use the fine focus knob to sharpen the focus quality of the image after it has been brought into focus with the coarse focus knob.
