What lens of a compound microscope is closest to the object being examined?
The 'object lens' in a compound microscope is closest to the object being examined.
Which lens of a compound microscope is the object being examined?
The object being examined is placed directly under the objective lens of a compound microscope. The objective lens is the lens closest to the specimen and is used to magnify the image of the object.

Which lens of a compound microscope is closet to the object being examined?
The lens of a compound microscope closest to the object being examined is called the objective lens. This lens is responsible for gathering light from the specimen and magnifying the image. It typically comes in various magnifications, such as 4x, 10x, 40x, and 100x, allowing for different levels of detail to be observed.
What is the difference between a compound microscope and an electron microscope?
Compound microscopes (also called compound light microscopes) employ light and an array of glass lenses to magnify an object. (This is distinguished from a simple microscope of one lens.) An electron microscope uses a beam of electrons to magnify an object. The lensing system employs electric and magnetic fields and is specialized for applications requiring much higher magnification. See related links.
Why are compound light microscopes?
Compound light microscopes are essential tools in biology and other sciences because they allow for the observation of small specimens at high magnification. They use multiple lenses to magnify an object, typically up to 1000x, enabling detailed examination of cellular structures and microorganisms. Their use of visible light makes them accessible and easy to operate, making them valuable in educational and research settings. Additionally, they are relatively affordable compared to other types of microscopes, such as electron microscopes.
What do microscopes use to change the appearance of an object?
Microscopes use lenses to change the appearance of an object. By adjusting the lenses, the microscope can magnify or reduce the size of the object and bring it into focus for clear viewing.

Who invented the microscope and what did they find out with it?
The first microscope was constructed by Antony van Leeuwenhoek in 1632-1723. His microscopes used single biconvex lens & were called simple microscopes. It had a considerable magnifying power up to 200 times. Robert hooke in 1635-1703, an English scientist, developed a microscope by using two lenses or achieving greater magnification. Such microscopes were later known as compound microscopes which magnifies an object up to a maximum of about 2000 times. He first examined a thin slice of cork under his microscope & observed that it was made of tiny boxlike compartments piled up together. This reminded him of the rooms, or cells, of monks in a monastery & so he said that the cork was made up of cells. The cells that he examined were all dead cells & they had only empty boxes or the walls. The invention of electronic microscope added further to the unknown facts about cells. It gave a magnification to over 200,000 times. It uses beams of electrons which are bent by magnets.
