What must be photographed or produced electronically?
Documents that need to be stored or shared electronically should be photographed or scanned, such as receipts, contracts, or ID cards. It is important to ensure that the electronic copies are clear and legible for easy access and reference.
What type of microscope can be used to study a viruses?
As viruses cannot be seen with the optical microscope, electron microscopes are used. All the "lenses" in an electron microscope are magnetic fields produced by electromagnets and/or electrostatic fields produced by electrically charged metal plates and/or rings.
How does the accelerating voltage affect the speed of charged particles in an electron microscope?
The accelerating voltage in an electron microscope directly affects the speed of charged particles. Higher accelerating voltage results in faster-moving particles, which can improve the resolution and clarity of images produced by the microscope.
What is used to bend electrons in an electron microscope?
Magnetic lenses are used to control the electron beam in an electron microscope. The magnetic field produced by the magnetic lenses deflects the energetic electrons. They are typically called magnetic lenses because they deflect the electron beam like optical lenses deflect light.
What is a characteristic of an image produced from a transmission electron microscope A. It is black and white. B. It shows the surface of objects. C. It does?
It is black and white.
Why there is more detail in an image produced using TEM than in an image from a light microscope?
An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes.

What are the characteristics of an image produced from a transmission electron microscope?
Images produced from a transmission electron microscope have high resolution, allowing for detailed visualization of internal cellular structures. They have a black and white appearance due to the interaction of electrons with the sample. These images provide information on the morphology, internal structure, and composition of the specimen.
What microscope provides sharp pictures of three-dimensional structures at high magnification?
Scanning electron microscope-An electron microscope that forms a three-dimensional image on a cathode-ray tube by moving a beam of focused electrons across an object and reading both the electrons scattered by the object and the secondary electrons produced by it.
What is the radiation used in an electron microscope?
Electron microscopes use a beam of electrons for imaging instead of light. The electrons are produced by an electron gun and accelerated through an electromagnetic field to create the necessary energy for imaging samples with extremely high resolution.
What is the principle of electron microscope?
There are two types of the electron microscope. First is called transmission electron microscope. It uses electrons passed through the sample to build a picture of the sample internal structure. Second type is scattered ("reflected" from the sample surface) electrons to build up a picture of the sample surface.
What is the source of illumination for an electron microscope?
Electron microscopes use a beam of electrons to illuminate the sample instead of light like in optical microscopes. These electrons have a much shorter wavelength enabling higher resolution images to be produced.
