A microscope (from the Ancient Greek: μικρός‚ mikrós‚ "small" and σκοπεῖν‚ skopeîn‚ "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy.Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes‚ the most common and first to be invented is theoptical microscope which uses light to image the sample. Other major types of microscopes

Guided Notes Activity Sheet Type of Microscope Most useful for viewing: Limitations of this microscope are: The microscope works by: Describe the detail that can be seen under this microscope. (You may find it helpful to draw one of the specimens viewed under the microscope.) Dissecting Microscope Organisms or objects at relatively low magnifications. You can only view oranisms that can be seen with the naked eye. It magnifys up to 40 times the size of the specimens serface by passing throught

polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites‚thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer and X-ray diffraction . The morphology of these composites was studied by scanning electron microscopy.

How was the Microscope Invented? The microscope is a machine used to see tiny‚ small things such as germs and bacteria. These small creatures are not seen by us but can be seen by a microscope. The three subtopics that will be mentioned are: 1) Who invented the microscope? 2) Why was it invented and What are the different types of microscope. The prediction made was that the microscope was a very important part of life in the middle-ages. People had very serious sicknesses at that

Period B 10/4/13 I. Title: Microscope Lab Report II. Purpose: The purpose of this lab was to teach us how to use a microscope‚ how to make a temporary wet mount‚ and how to stain a slide. The purpose of this lab was also to teach us how to use and measure with a microscope. The purpose of this lab was also to teach us how to draw what we see in a microscope’s field of view. III. Procedure: A. How to use a Microscope When going to take out the microscope‚ make sure you carry it back to

independently used the microscope to identify the cause of the bubonic plague. Compound microscopes—microscopes that use more than one lens—were invented around 1595. These first microscopes usually magnified objects only 20–30 times their original size. But as you will learn in the next few activities‚ even this level of magnification was enough to discover a world of new scientific ideas. By 1840‚ Italian physicist Giovanni Amici (a-MEE-chee) had invented the oil-immersion microscope which could magnify

film. Large-area SiNWs with average diameters of 20 nm down to 8 nm and wire densities as high as 1010 wires/cm2 were accomplished. These SiNWs were single crystalline and vertically aligned to the (100) substrate. It was revealed by transmission electron microscopy that the SiNWs were of high crystalline quality and showed a smooth surface. In recent years silicon nanowires (SiNWs) have attracted much attention1‚2 due to their many unique properties and potential applications as building blocks
