Definition of the parts of the microscope 1. Stage The horizontal surface upon which the slide is placed is called the stage. The slide is held in place by spring loaded clips and moved around the stage by turning the geared knobs on the stage. Th stage has two perpendicular scales that can be used to record the position of an object on a slide. This is useful if you want to quickly relocate an object. 2. Coarse adjustment The coarse adjustment knob located on the arm of the microscope

The microscope is considered one of the most useful and important scientific inventions known to ’man’. The microscope was invented by Anton van Leeuwenhoek during the seventeenth century. Leeuwenhoek was not a scientist by profession. Initally he made a living selling clothes and buttons‚ but spent his spare time grinding lenses and constructing microscopes of remarkable quality‚ such as the light microscope. The light microscope could magnify cells‚ for instance in plants so you could see a clearer

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

Daniel Chandler tells us that a sign consists of two parts: the signifier and the signified. The signifier is the form that the sign takes‚ and the signified is a reaction of the signifier. For example: if the signifier is a symbol‚ then the signified could be a concept in the mind pertaining to that symbol. Knowing that there are tens of thousands of different types of signs. Charles Pierce categorized them into 3 modes. The symbolic mode is one where the signifier is not directly related to the

1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution

Assignment: Paragraph Response A Secret Lost in the Water & Mirror Image What is "Self-discovery"? The dictionary defines discover as "to gain sight or knowledge of (something previously unseen or unknown)". In the short stories "A Secret Lost in the Water" and "Mirror Image"‚ there is a co-relation in the theme of self-discovery as well as few other similarities. Such as there are similarities‚ there also differences in between the two. The follwing paragraphs will discuss the topics above

1. (a) Indications -The stenopaic slit refraction is useful for confirming the results of other refraction techniques for patients with irregular astigmatism or reduced visual acuity. - It is helpful for patients who have difficulty understanding the complex instructions associated with other subjective techniques. -It is important to note that‚ like the pinhole‚ the stenopaic slit may be used diagnostically to determine a patient’s potential visual acuity. -The astigmatism present in the patient’s

INTENSITY OF SUNLIGHT The Intensity of the sunlight is measured at different timings by using Lux Meter which measures the intensity of illumination. The Intensity of light is measured in Lux which is the S.I unit of measurement of intensity of illumination of a source. The results are tabulated in the Table 4 and plotted as shown in the Figure 7. Table 4 Intensity of Sunlight Time Intensity of Sunlight(LUX) 9.15AM 54900 11.15AM 73400 1.15AM 81000 3.15AM 64500 5.15AM 35100 Figure 7 Plot of Intensity

Name: Skill Sheet 17.3 Thin Lens Formula Here you will become familiar and practice with a mathematical formula called “the thin lens formula.” This formula gives scientists a way to calculate the location and the size of an image that is produced by a lens. 1. What is the thin lens formula? When you use the thin lens formula‚ you assume that the thickness of the lens is very small compared with the distance between the lens and the object or the image. The formula applies both to convex or converging
