A phase-contrast microscope differs from a brightfield microscope by having a?
Phase-contrast microscope utilizes phase shifts in light passing through a transparent specimen to enhance contrast, making transparent objects more visible without staining. Brightfield microscopes rely on absorption of light by the specimen to create contrast, typically requiring staining to visualize transparent specimens effectively.
What is a streak plate?
A streak plate is a surface of unglazed ceramic, used to find the true color of a mineral specimen by drawing the specimen across it. The color of the resultant powder is referred to as the streak or streak color of a mineral.
The relationship of the cell and the microscope?
A cell is a structure which is present inside everything in this world and a microscope is an electronic machine which enables people to see these cells. A cell is classified into plant cell and animal cell and a microscope is classified into electronic microscope and ordinary microscope. Plant cell has cell wall and cell membrane and animal cell has vacuole and nucleus. Electron microscope uses electrons and an ordinary microscope uses simple glass plate. There is also another type of microscope called light microscope which uses light.
Why do you need a drop of water to prepare slides when using microscope?
Because an air bubble, trapped between the slide and cover plate, shows as a dark'blob' under magnification. Using a drop of water to 'seal' the slide & cover plate together excludes the air - making the specimen more visible to the user.
Can you determine whether a agar deep culture is pure by visually inspecting it without a microscope?
The short answer is no. Microorganisms are just that - microscopic, and the naked eye can not determine between different species, especially in a broth culture. Maybe on a plate, where the colony shapes, sizes, viscosity, and color can be determined, but a broth culture usually needs to be streaked onto a plate to determine if it is pure or not.
What is a glass plate and how it is use?
== == You put a specimen on a glass plate and then view the specimen under a microscope. It acts sort of like a slide.
What is the function of the rotating plate of a microscope?
The rotating plate, also known as a stage, holds the specimen and can be rotated to view different areas. This allows for precise positioning and examination of the specimen under the microscope.
Where are slides placed on the microscope?
condensor plate
Where are slides placed on microscope?
condensor plate
What did the first microscope look like?
Almost like a musical instrument One of the first (see the link below) was a brass plate with a glass bead for a lens, behind the glass bead was a needle on a screw for the specimen.
What specimen can be seen in the occular lenses?
The one you placed on the viewing plate.
What is glass plate as laboratory apparatus?
A glass plate in the laboratory is a flat, smooth piece of glass used for various applications such as microscopy, culturing cells, mixing substances, or as a base for other experimental setups. It provides a stable, clear surface for working with samples or conducting experiments. Glass plates can come in different sizes and thicknesses to suit different laboratory needs.
Does the napkin ever go to the right of the plate?
If placed on the table the napkin always goes to the right of the plate, but also can be folded and placed inside an empty wine glass.
Rectangular glass plate used to view samples of water or other materials?
The rectangular glass plate you are referring to is likely a microscope slide. Microscope slides are commonly used in laboratories to hold samples for viewing under a microscope. They provide a flat and transparent surface that allows light to pass through the sample for observation.
How far from the edge of the table do you place your plate?
There is no set rule for the placement of a dinner plate, but a good host will set a salad or bread/roll plate to the top left and a soup bowl and plate can be placed upon the top of the dinner plate if desired. A glass of water and/or wine can be placed at the top right.

Phase-contrast microscope utilizes phase shifts in light passing through a transparent specimen to enhance contrast, making transparent objects more visible without staining. Brightfield microscopes rely on absorption of light by the specimen to create contrast, typically requiring staining to visualize transparent specimens effectively.
Thin-film interference occurs when one clean glass plate it placed on top of another glass plate What does the thin film consist of in this case?
In this case, the thin film consists of the air gap between the two glass plates. When light reflects off the top surface of the top glass plate and the bottom surface of the bottom glass plate, interference patterns are created due to the difference in optical path lengths caused by the varying thickness of the air gap.
