Contrast the way light microscopes and electron microscopes magnify objects?
Sample illumination is achieved in different ways in a light and electron microscope.In a light microscope, the sample is illuminates with light (photon energy)In an electron microscope, the sample is illuminated by a beam of electrons.Devon
How do you create my specimen signature?

What microscope was used to create the first image of an atom?

What does a mixture and compound create?
A mess.
What is the resolution power of a transmission electron microscope?
The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to "see through" the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in "scanning" the beam of electrons across the sample. TEM focus a beam of electrons through a specimen while SEM focus a beam of electrons onto the surface of a specimen and the image provided is 3-Dthe transmission microscope magnifies 300,000 more times and the scanning microscope only magnifies 100,000 more the transmission gives the image of the inside and the scanning microscope gives a 3D image of the surface of the specimen
What are the functions of a microscopes diaphragm?
The diaphragm of a microscope focuses the light into the eye piece to create optimum viewing of the specimen.
Why is immersion oil is used in a slide?
Immersion oil forms a path between the lens and the specimen for the light to follow. The space between the lens and specimen at high magnification is tiny. If you didn't use oil, the light would bend away from the lens, and you wouldn't be able to see anything.
Types of microscope and their uses?
Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.

What type of microscope did Leeuwenhoek create with one lens?
The simple microscope, defined as having one lens, was enhanced by Leeuwenhoek. Many of the compound (multiple lensed) microscopes were blurry, but Leeuwenhoek ground his own lenses.
Who invented the microscope and what made him to create the apparatus?
An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Hans Janssen. Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625
When did Robert hooke create this first microscope?
He didn't create the first microscope, Zacharias Janssen did.
