Lori Stenbeck Bio K121 June 7‚ 2012 The Microscope Introduction: The purpose of a microscope is to see either enlarge images of small objects and or make seen what is invisible to the naked eye. We have two types of microscopes available in the lab. The dissecting microscope is designed to study objects in three dimensions at low magnification. The compound microscope is used for examining small or thinly sliced sections of objects under magnification that is higher than the dissecting microscope

click switch views to look into microscope. When looking through the microscope adjust the ocular lens until the two circles of light emerge as one. Adjust the coarse focus down until specimen appears. Use the fine focus knob for clarity of the image‚ xy controls to get the area of interest into view‚ and the iris to control the brightness of the image. Once image is focused the objective lens may be changed and you can then begin to view the specimen within a higher power of magnification

Notes for WK2 – 10 September Lesson 1 * State the resolution and magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object

to raise your reputation is like trying to raise brownie points. If people haven’t realized it’s not about your reputation. A friend could say “This guys so smart”. Some people say that that raises your reputation. Well If another guy see you and asks his friend who he is and he says “That’s Jim Bob… he’s probably the smartest kid in our grade”. In all reality in comparison with Jim Bob and the other guy‚ the other guy could be twice as smart as him. Well… where’s his reputation now. I find the

Reputation in Othello Reputation is the general way in which people perceive you to be based off of facts and opinions. Your reputation defines you as a member of society‚ and it can be used towards your benefit depending on if your reputation is good or bad. A good reputation often enables one to gain trust and respect from others‚ while a bad reputation may lead one to be considered as a treacherous and disloyal individual. Reputation plays an important role in Othello‚ as Iago uses his own reputation

Compound and dissecting microscopes have many similar parts‚ including a lens‚ stage‚ focus knob and coaxial controls that allow you to adjust the distance between the lens and the stage. 10.

telescope to observe the sky and planets like Galileo but did it to further study the field of optics. Our reflecting telescope is similar to Newton’s that he made in 1668. Both ours and Newton’s consisted of a flat mirror‚ a spherical mirror and a convex lens. Our telescope also suffered from the repercussions of spherical aberration. Below is a drawing of the concept of our telescope and Newton’s telescope: Drawing 1 Isaac Newton (1642-1727) Isaac Newton‚ often referred to as Sir Isaac Newton

microscope focuses light on a tiny bright spot of the specimen‚ the microscope accumulates light from the well-illuminated specimen in the stage of the microscope. The small objective lens then brings the image of the object into focus within the microscope’s tube‚ and is then magnified by a second lens‚ called an ocular lens or the eyepiece. The specimen in an optical microscope can be rather thick. In contrast‚ unlike the light microscope‚ the electron microscope visualises objects using a thin beam
