Light microscopes have a low resolution‚ therefore if the magnification

The microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590‚ they have improved our knowledge in basic biology and biomedical research‚ as well as many other things‚ all of which are important. The smallest object a human can see with the naked eye is 0.2 mm‚ for example‚ algae cells. The light microscope‚ however‚ allows us to see things almost 1000 times smaller that what

disadvantages of a light microscope and electron microscope? Some of the disadvantages of the light microscope include‚ that since it send light‚ the light waves are diffracted as they pass through the matter. Because of this‚ light microscopes can only produce clear images of objects to a magnification of about 1000 times. Another problem is that since most living cells are nearly transparent‚ you can’t see them. So you have to use dyes to stain them. The advantage of using a light microscope however is that

experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X. A microscope must be used to see and study

OPTICAL MICROSCOPE Introduction The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology‚ microbiology‚ biotechnology‚ pharmacology‚ forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words‚ Optical microscope is a

Page 1 INTRODUCTION The purpose of lab 1 was to learn about general bacteria’s and the use of a compound microscope. The microscope contains biconvex lenses‚ bi- meaning two. The basic frame of the micro scope consists of a base‚ a stage to hold the slide‚ an arm for easy carrying‚ and a body tube for transmitting the magnified image. The light source is in the base. One can focus on the image of an object by moving the lens closer to the slide or the stage closer to the objective lens‚ using
