Any organic substance or sample thin enough to let light through.
Photomicrograph
As the cells are transparent, the components cannot be seen clearly through a microscope. We stain the cell so that we can see the components of the cell clearly through a microscope.
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
In biology, the eyepiece in a typical light microscope is used for magnifying the image being viewed (the field of view) by 10 times. Secondly, the eyepiece also has a scale on it which is visible when you look down through the microscope at an image, or at your field of view. This scale has divisions on it which you can use to measure the length of the cellular structures you are looking at. So basically, the eypiece magnifies the image and has a scale on it which you can use to measure the structures in the cell.
Because it uses electrons instead of light, and light is required for color to be present.
Objects viewed through a light microscope look a lot bigger.

You look through a microscope through a part called the eyepiece.
With a normal light microscope, you can't look directly at your finger. It's just too thick for light from underneath to pass through, to reach the microscope lenses. It might be possible to scrape off thin layers of dead skin and put them on a slide to view through a microscope, though.
light microscopes shoe only black and white pictures. When a compound microscope shows color when you look through the eye-piece.
Plant cells, animal cells and bacteria can be visualized through the light microscope. Although some of these samples may require staining in order for the observer to see them, the magnification offered by the light microscope is sufficient to look at the morphological structures of the types of cells mentioned above
no, because the penny is not see-through. The compound light microscope uses a light and all you would see is a dark spot that used to be the penny.

A microscope is a device that magnifies very small items so they can be seen and studied. A light microscope does this by using light passed through a slide containing whatever you are trying to look at, then through lenses and mirrors to an eyepiece. another type of microscope is the electron microscope which passes electrons (much smaller then waves of light) through the substance to a reciever that then projects the image onto a computer screen allowing much greater levels of magnification.
A diaphragm regulates the amount of light entering the microscope. Stage opening allows light to pass through the stage of the microscope.
