What type of microscope provides the greatest resolution?
Depth of field in a microscope refers to the distance between the nearest and the furthest objects that produce a distinct image of a specimen. It is usually very short and is measured in microns.
When was the electron microscope invented?
1928 i believe by the Germans... someone check me on that... it wasnt the electron microscope we know today but it was the same concept only it magnified by a small 17 times... it has be improved since then
What is the working mechanism of electron microscope?
Transmission: A beam of electrons pass a sample and is absorbed in electron-dense structures, which look black in an image. Scanning: samples are coated with metal and scanned with a beam of electrons.
How does the working distance affect the size of objects that can be viewed under a stereo microscope?
The working distance of a stereo microscope refers to the distance between the objective lens and the specimen. A longer working distance allows for larger objects to be viewed, as there is more space between the lens and the specimen. Conversely, a shorter working distance limits the size of objects that can be viewed due to the physical constraints of the microscope's design.
What is the optimal working distance for a microscope to achieve the best focus and clarity of the specimen?
The optimal working distance for a microscope to achieve the best focus and clarity of the specimen is typically around 0.1 to 0.2 millimeters. This distance allows the microscope to capture clear and detailed images of the specimen.

Was the electron microscope invented in Germany?
Yes. German engineers Ernst Ruska and Max Knoll built the first machine in 1931 in Germany. It didn't outperform the best optical microscopes, but it served to demonstrate the ideas. A couple of years later, Ernst Ruska (working for Siemens in one of their German locations) built an electron microscope that surpassed the resolution limits of an optical microscope. Wikipedia has a nice article on the history of the electron microscope, and a link is provided to that post. You'll find it below.
What is the construction of simple microscope?
A simple microscope consists of a single lens, typically a convex lens. The object being viewed is placed close to the lens, which creates an enlarged image that is viewed directly by the observer's eye. The lens and the object are positioned so that the focal point of the lens falls on the object, allowing for magnified viewing.

What was Leeuwenhoek's first job prior to working on the microscope?
Antony Leeuwenhoek's job prior to working on the microscope was being a shopkeeper.

What is construction runoff?
runoff caused by construction working
What do microbiologists use while they are working in the lab?
Microbiologists use many job specific tools to complete their investigation. Most importantly , a high end electron microscope with proper mounting wares are a essential.
Can you drive a vehicle without a working transmission?
Of course not. Without a working transmission you are going nowhere.
What type of experience is needed to get a job working in construction project management?
In order to get a job working as a construction project manager, you will need extensive experience working as a foreman. You will also need a bachelor's degree in a construction related field.
