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

PRACTICAL 3 QUESTIONS PART 1 Q 1. What is the diameter of the field of view of your microscope using the x10 objective (i.e. at a magnification of x100)? The diameter of the field of view using the x10 objective is 1800 µm. Q 2. What is the diameter of the field of view of your microscope using the x40 objective (i.e. at a magnification of x400)? The diameter of the field of view using the x40 objective is 400 µm. Q 3. What is the ratio of magnification between the x10 and x40 objectives?

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

In the case of Wernicke’s production‚ the mirror stands as the main motive always as its background. It has different meanings for this production. As I already mentioned‚ the mirror background reflects the different images of Vienna‚ singers on the stage and the audience. At the first scene‚ the mirror is directed forward and reflects the stage and the audience. But soon later‚ it turns inside and reflects the image of historical red bedroom of the Marschallin on it. At the end of the first act

While experimenting with the speed of light‚ I noticed that the light being refracted was slower when it shined through a denser medium. For example when the higher medium was water and we were comparing it to air‚ the speed of the light being refracted was 0.75 c. If we were to switch the medium to glass‚ which is more dense than water‚ the speed of the light decreased to 0.67 c. For two of the mediums they were both placed at the same angle when we started shining the light and as the outcome

Fiber Optic Safe Working Procedures Most of the standards‚ created by industry groups to insure product compatibility‚ they are not “codes” or actual laws that must be followed to be in compliance with local ordinances. The only mandatory standard is the NEC. The NEC specifies fire prevention standards for fiber optic cables. They are however‚ the standards we must follow. Installation Hazards: When installing burial or aerial cable‚ cables containing conductive materials could pose a potential

Fiber Optic Safety Rules 1) Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2) Do not smoke while working with fiber optic systems. 3) Always wear safety glasses with side shields. Treat fiber optic splinters the same as you would glass splinters. 4) Never look directly into the end of fiber cables until you are positive that there is no light source at the other end. Use a fiber optic power meter to make certain the

Leber’s Hereditary Optic Neuropathy (LHON) is a kind of genetic disorder that caused by the pathogenic variants in mtDNA (mitochondrial DNA) leading to a bilateral visual loss during young adult life‚ especially in males. Mitochondrial DNA is found in mitochondria which breakdowns carbohydrates and fatty acids to generate energy so that the body cells can use. Mitochondrial DNA is inherited maternally‚ it is because the paternal mitochondria in sperm have disappeared during the early embryogenesis
