how to use a microscope and oil immersion lens while observing prepared bacterial slides and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides with 10x and 40x objctives lens. In each slide the differences was magnification

PC1222 Fundamentals of Physics II Tutorial 8 1. Refraction of Light I. When a man stands near the edge of an empty drainage ditch of depth 2.80 m‚ he can barely see the boundary between the opposite wall and bottom of the ditch as shown. The distance from his eyes to the ground is 1.85 m. (a) What is the horizontal distance d from the man to the edge of the drainage ditch? (b) After the drainage ditch is filled with water as shown‚ what is the maximum distance x the man can stand from the edge

microscope. The term "compound" means more than one lens is used. In the compound microscope you have two lenses. The primary lens is the one closest to the object and then there is the secondary lens‚ which is furthest from the object. The secondary lens is used to magnify the image of the primary lens. The primary lens is aimed at the condenser‚ or stage‚ and this is where the object to be magnified in the form of a slide is placed. A modern compound lens can magnify the original diameter of specimens

compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes are inexpensive and relatively easy to use

Lab No. 2: The Microscope Light microscopy The bright field microscope is best known to students and is most likely to be found in a classroom. Visible light is focused through a specimen by a condenser lens‚ then is passed through two more lenses placed at both ends of a light-tight tube. The latter two lenses each magnify the image. Limitations to what can be seen in bright field microscopy are not so much related to magnification as they are to resolution‚ illumination‚ and contrast

look through at the top of the microscope. Typically‚ standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available‚ typically from 5x-30x. * Eyepiece tube holds the eyepieces in place above the objective lens. Binocular microscope heads typically incorporate a diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not need a diopter. Binocular microscopes

viewing the onion cell through the microscope. Place the microscope slide onto the microscope stage. Place the microscope stage clips onto the slide. This will prevent the microscope slide from moving during observation. Ensure that the microscope’s lens magnification is at either x10 or x40. Look through the eye-piece and draw what you can see. Post-Practical - After the Experiment/Tidying away equipment; Turn the focusing handle so that the microscope lenses are at the top of the microscope.

capable of bending when passing through an object‚ when it enters the lens‚ the light gets reversed and magnified through the prisms‚ and eventually enters your eyes. Our eyes are also binocular instruments. This means they take to images and bring them together to form a single‚ high quality image. Binoculars consist of two small telescopes mounted side by side‚ one for each eye‚ and a focusing mechanism. By having a lens system for each eye‚ these instruments provide three-dimensional viewing
