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

plug it into an outlet. 3. Using Figure 2.2 as a guide‚ locate and identify each ocular and objective lens. Record the magnification of each lens and the total magnification. Total magnification is calculated by multiplying the magnification of the ocular (10x) by the magnification of the objective (10x‚ 40x‚ 400x). Lens Used 10x objective lens 40x objective lens 100x objective lens with oil Lens Magnification Total Magnification 4-2 Figure 4.2. Parts of a Microscope 4-3 Figure 4

The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

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

There are three main designs of telescopes; refractors‚ reflectors‚ and a catadioptric. The refracting telescope is one of the most common telescopes. The refractor telescope captures an image through the lens and bends it. After it is bent‚ it is sent to the focal point and modified by the lens and viewed through the eye piece‚ (Telescopes‚ 2013). The refracting telescope is among one the most popular telescopes because the strengths of the telescope. This type of telescope is long lasting‚ useful

shape and position of the two lenses in a compound light microscope. Light passes through the convex lens and is bent. The light continues on to the next lens and are bent again. The initial pass through the lens caused the light to intersect but the secondary pass of light through the second lens causes them to be parallel. The light from the top of the image is now seen in the second lens at the bottom and it will appear inverted. The color of the threads are cream color‚ red and blue. They

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
