A light microscope uses visible light to magnify and view specimens, offering lower magnification and resolution compared to a scanning electron microscope (SEM) which uses a focused beam of electrons to image the sample, providing higher magnification and resolution. SEM can produce 3D images of the sample surface while light microscopes typically provide 2D images.

What is the Iris for the optical microscope?
The iris in an optical microscope is a diaphragm located beneath the stage used to control the amount of light that passes through the specimen. By adjusting the size of the iris, the amount of light entering the microscope can be regulated to optimize the image quality and contrast.
What function is performed by the diaphragm of a microscope?
The diaphragm of a microscope is used to control the amount of light passing through the specimen. By adjusting the diaphragm, you can regulate the brightness and contrast of the image, helping to improve visibility and clarity.
What parts compose the magnifying system in microscope?
The magnifying system in a microscope typically consists of the objective lens, eyepiece lens, and sometimes a condenser lens. The objective lens is responsible for capturing the image of the specimen, while the eyepiece lens further magnifies the image for the viewer. The condenser lens helps focus the light onto the specimen for clearer viewing.
What is the scientific name for blue fires?
The scientific name for blue fire is "Cherenkov radiation." It is a type of electromagnetic radiation emitted when a charged particle, such as an electron, travels through a medium at a speed greater than the speed of light in that medium.
What is the scientific name for bending light?
Refraction or Refraction of light is the scientific name for the bending of light. Same Thing.
What types of microscopes?
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
What is a feature of the scanning electron microscope and is not a feature of the light microscope?
It uses electromagnets.
The nucleus of a cell can be viewed through what kind of microscope?
The nucleus of a cell can be viewed through a light microscope or an electron microscope. The electron microscope provides higher resolution and magnification compared to a light microscope.
Explain the difference between a light scanning and electron microscope?
A light microscope uses visible light to illuminate a sample and magnify its image, making it suitable for observing living cells and larger biological structures. In contrast, an electron microscope uses a beam of electrons to create a highly detailed image of the sample at a much higher magnification, enabling the visualization of smaller structures such as viruses and proteins.
Which is a feature of a light microscope and is not a feature of a scanning or transmission electron microscope?
It uses a combination of lenses.
Different types of microscopes?
Some types of microscopes include optical microscopes, electron microscopes, and scanning probe microscopes. Optical microscopes use visible light to magnify objects, while electron microscopes use beams of electrons. Scanning probe microscopes create images by scanning a probe over the surface of a sample.
What are the Types of microscopes?
There are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, Transmission Electron Microscope, Dissection microscope, etc,but all together there are about 20 different types of microscopes.
What tool allowed scientists to study cells?

What is the light source for the SEM system?
The light source for a Scanning Electron Microscope (SEM) is emitted by a heated tungsten filament or a field emission gun. These sources produce a beam of electrons that is focused and scanned across the sample to generate the image.
What are two main types of electron microscopes?
there are several kind of different , we can separate : 1- Methods of analysis 2- properties of Methods of analysis 3-properties of their structure 4-resolution and resoiving power of their (by : S.M Zendehbad)
