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

The Observation of organism in a drop of pond water (Paramecium) under LPO and HPO Compound Microscope Doreenda A. Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually

(Most people were creating telescopes) • The first microscope was 6 feet long!!! • The Greeks & Romans used “lenses” to magnify objects over 1000 years ago. The History

use of scanning electron microscopy which produces high resolution‚ 3-D images‚ it can be seen that Lindow Man had a short trimmed moustache and beard and his stomach contents were also revealed. In his stomach it revealed that he had bran and wheat and plenty of other nourishable foods which indicate to the archaeologists and scientists that Lindow Man was not poor and was possibly from the middle to upper class. Another scientific technique that was used was the use of electron spin resonance spectroscopy

Before the creation of microscopes‚ misconceptions about how organisms were originated arose. The idea of spontaneous generation‚ a theory held for nearly two millennia‚ proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory‚ until the creation of the microscope. In 1663‚ Robert Hooke‚ proposed that organic matter was composed of what he called‚ cells. He was able to view these cells as he used a simple microscope‚ which allowed him

and a compound microscope effectively and efficiently (lighting‚ focus‚ magnification‚ resolution)‚ and to practice manipulating small organisms Principals: 1. The smallest object viewable under a compound light microscope is limited by resolution or resolving power (ability to distinguish between two nearby points) and not magnification. 2. Mircoscope resolution is limited by the wavelength of the source of illumination (visible light‚ in the case of an optical microscope) and the numerical
