Within the laboratory experiment the external and internal functions of the microscope were observed. Also the specimens magnified through the microscope. The opportunity to create a specimen was given through the rubbing of the cheek cell. The skill of focusing images improved through the course of the experiment
Objective
The Microscope is a scientific instrument that enlarges images of small objects that are difficult to visualize with one’s bare eyes. The microscope consists of two magnifying lenses, the ocular and the objective lense, which enhances the visibility of a specimen that is to be examined. The main objective of the laboratory experiment to understand the demonstration of the required procedures used while using the …show more content…
Is finding out the total the total magnification, which is done through multiplication of the number on the eyepiece and the objective magnification.
Discussion
The most common microscope is the compound which is used in biology and many other sciences courses, this common microscope uses more that one lens which allows for a more complex resolution of the specimen to be observed, which was shown in the first section which involve the letter “e”, the images that were observed under the light microscope were reversed and inverted, which occurs because the when the light passes the lens the image gets inverted since the lense are convex causing the image to “flip”, which is what occurred with the specimen when the letter “e” that was placed under the stage …show more content…
This microscope allows for a more in depth observation of the specimen. In addition there is also another type of microscope known as electron, which use beam of electrons instead of light to produce images through the microscope. These microscopes present clear images, which is essential for smaller objects. This is a benefit that is not found in the compound microscope. The electron microscope goes as far to be classified into two types: the transmission electron microscope (TEM) and the scanning electron microscope (SEM). The difference is that the TEM shines beams of electrons through a thin specimen and the SEM scans a narrow beam of electron across the surface of the specimen. The development of microscope has since 1590 when a Dutch eye maker by the name of Zaccharis Janssen creates a forerunner of the compound microscope and the telescope. The development extended into 1936 when Erwin Wilhelm Muller invented the field emission microscope. The sole purpose of the cumulative development of the microscope has
