Adjust the coarse focus as best as possible and then adjust the fine focus knob til it looks really good

What can cause an image to appear blurred using a microscope?
The light so bright.
What is the purpose of a mirror in a microscope?
The purpose of a mirror is to reflect light through the diaphragm, the specimen, the objective lens, and body tube and into your eye so you can see the image. Never use sunlight when using a microscope with a mirror, as it could damage your retinas.
What concentrates the light on the objective being observed when using the microscope?
Condenser
When using a light microscope if you want the field of view to be larger you would use?
.
Microscope using two lenses?
compound microscope

What is the difference between an electron and a light microscope?
A light microscope is a simple microscope that magnifies light that it collects and spread onto a screen digitally or optically. Electron microscopes is a microscope that fire electrons onto a object then it is bounced back to form an image. It enlarges the image when it is bounced back. It is fired consistently to receive a constant image. It is viewed with a electronic screen. When the electron is fired it creates light which bounces back as well. It can magnify much bigger than a optical microscope.
Compare and contrast a compound light microscope and an electron microscope?
Light microscope: 1. Uses a beam of light that is focused using glass lenses. 2. Magnification is moderate -- not as much as electron microscope 3. Produces a color image since it uses light 4. Can look directly at the specimen with our eyes Electron microscope 1. Uses a beam of electrons that is focused using magnets. 2. Magnification can be extremely high and show details that are not possible with the light microscope 3. Produces a grey-scale image because color requires visible light 4. Image must be seen on a monitor or in a photograph because we don't see electrons.
Why Images observed under the light microscope are reversed and inverted?
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).

Why there is more detail in an image produced using a TEM than in the 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 is the difference between a Light Microscopes and an Electron Microscope?
The optical microscope is the most common. It uses light to image a sample that is too small to be seen by the naked eye.The scanning electron microscope examines the surface of objects using an electron beam and measuring reflection.Short Answer = Resolution.
Which is the simplest the light miicroscope or the electron microscope?
light microscope is the simplest, in manufacturing and using
Can atoms be seen by a microscope?
No. to viewing a phenomenon you need to send light (photon) to it and then see reflected light( photon) as the atom particles (electron,neutron,proton) are in order of photon, your sent light changes their conditions and you see none
What makes a microscope work?
There are three types of basic microscopes: Electron Microscopes, Simple Light Microscopes, and Compound Light Microscopes. Simple [light] Microscopes work by focusing light through one lens. The most common lens, the Convex Lens, works by being thicker in the center than the edge. This bends the light, altering the image as it hits the second lens, your retina. A Compound [light] Microscope works differently. It is the most common microscope for everyday use, using a mirror to shine light up through a slide containing a specimin. Next, the ray of light shines up through a series of lenses, bending the light and multiplying the magnification and resolution levels of the image, until it hits your retina. Robert Hooke used a very complex compound microscope to observe cells through a thin slice of cork wood. The Electron Microscope is the most technologically advanced and, in my opinion, the coolest type yet. In fact, the electron microscope was so complex that it was not discovered until the late 1930's. It uses a beam of electrons instead of light to magnify an image. This allows you to get a much closer image with much higher resolution than with a regular light microscope. The most complex light microscope can only magnify an image up to 5000 times. An electron microscope can easily double that, a recently founded electron microscope can magnify an image up to 150,000 times. To work, this microscope actually borrows electrons from atoms, and as long as they return the electrons to the atoms, there is still perfect balance.
