Question

Mention any two uses of a simple microscope.

Answer 1

Hint: The microscope is the device is the optical instrument which is used to see the very minute objects, or micro particles, or microorganisms. So, the microscope is the optical instrument which is used in all the branches of science.

Complete answer:
The simple microscope is the microscope which is a magnifying glass that consists of the double convex lens with very small focal length. The example of the simple microscope is the hand lens and the reading lens is the simple microscope. When the object is kept near the lens of the microscope, the object is visible as bigger. The formed image in the lens is virtual but it is not projected on a screen like a real image.
The part of the simple microscope is eyepiece, base, tube, objective lenses, revolving nosepiece, diaphragm, stage, stage clip, coarse adjustment knob, fine adjustment knob, arm, power switch and condenser. Each and every part has its own specific objectives and uses. The eyepiece is the lens which is used to study the samples and it has the magnification of the $10X$ to $15X$. The base provides support to microscopes. The tube is used to connect the eyepiece and lenses.
The objective lenses are the number of lenses which are used to increase the magnification of the microscope. The stage is the place which provides the samples to fix. The stage clip is used to hold the samples. The adjustment knobs are used to focus the samples. The power switch is used to turn on the microscope. The condenser is used for the lights.
Uses of the simple microscope:
1. It is used in the study of pedology, which means the study of the soils.
2. It is used in the jewellers to see the fine parts of the jewels.

Note: The simple microscope uses the convex lens, the convex lens refracts the light rays and converges it to the point where the object is seen clearly. In modern microscopes, a greater number of the lenses are used so that the very minute particles are also seen.
