Answer:

1. The light source for the microscope is the microscopic illuminator, which is located at the bottom. It replaces a mirror and absorbs light from a low-voltage external source of around 100 volts. It is also like a lamp that you turn on and off using a switch.

2. The eyepiece, also known as the ocular, is the lens that you glance through at the peak of the microscope. Regular eyepieces usually have a 10x magnification capacity. Eyepieces of various powers, ranging from 5x to 30x, are accessible as alternatives.

3. The sample to be examined is placed on the stage. When operating at high resolutions and fragile motions of the sample slide is necessary, a mechanical stage is used.

4. The coarse adjustment knob on the microscope's arm raises and lowers the stage to put the sample into position. With only a slight turn of the knob, the gearing function of the modification provides a significant vertical movement of the stage.

5. The fine adjusted knob is located within the coarse adjustment knob and is used to put the sample into clear perspective at low power and for all focusing at high power.
