Advantages And Disadvantages Of Glass Fiber Optics

The concentrations and absorbances of the red and blue dyes were used to find the concentration of the purple dyes. From the graph of the blue dye, the linear equation for absorbance was y = mx + b. From that formula came the equation y = 7.915 x 104 (x) + 0.02489, where y represents absorbance, m is slope, x is concentration/molarity, and b is the constant/y-intercept. The same set up was performed for the red dye, but the equation produced was y = 1.045 x 104 (x) +.001298. The equations found when graphing absorbance vs. concentration were used to find the concentration of the purple dyes. The absorbance for purple dye 3 on the red wavelength of 470 nm equaled 0.149 and 0.818 for the blue wavelength of 635 nm. For purple dye 1

From this graph and chart we can see that the higher the concentration the higher the absorbance, all the different concentrations were tested at the same wavelength (625nm). Also we can determine our unknown substances concentration by using the absorbance we got for it. The red dot on the graph followed by the line towards the horizontal axis indicates that the concentration of fast green was 34% or 5.1x10-3.

When a beam of sunlight passes through a specially shaped glass object called a prism, the rays of different wavelengths are bent at different angles. The bending breaks up the sunlight into a beautiful band of colors. This band contains all the colors of the rainbow and is called the visible spectrum. At one end of the spectrum, the light appears as violet. It consists of the shortest wavelengths of light that we can see. Farther along the spectrum, the light has increasingly longer wavelengths. It appears as blue, green, yellow, orange, and red, each shading into its neighboring colors in the spectrum. The longest wavelengths of light that we can see appear deep red in color. Some descriptions of the spectrum also mention the color indigo, which is closely related to blue, between violet and blue.

The wavelength of the light should be a different color from the solution’s color. This is because if the color of the wavelength of the light is the same color as the solution’s color, then the color would not be absorbed. The only way that a solution can absorb a color is if the color of the light’s wavelength is its complementary (opposite) color. The color of the light chosen for this experiment was blue because the wavelength was set to 430nm, which corresponds to blue's wavelength. The color of the FeSCN2+ complex ion is blood-red.

Non Conductive: A serious concern with outdoor cables in certain computer networks is they can be hit by lightning, causing destruction to wires and other cables that are involved in the network. Fiber optic cables can be made non-conductive by avoiding metal in their design. These kinds of cables are economical and standard for many indoor applications. Outdoor versions are more expensive since they require the special strength members, but they can still be valuable in eliminating ground loop and protecting electromagnetic equipment from surge damage.

Grass and Soil have a moderately high reflectance they absorb about 65% and reflect about 35%. The spectral reflectance for the grass and soil typically increases when the wavelength increases, then it stays relatively constant and it increases again.

When you use a spectrophotometer you should not set the wavelength of light to be the same color of the solution. This is because if you set the wavelength to be the same color of the solution then no light will be absorbed. The reason why no light will be absorbed is because the color you see is the wavelength of light that is being reflected so you must set the wavelength to be the complementary color. The wavelength of light that was chosen for the lab was 450nm which coincides with a very dark blue color. The reason why choosing a dark blue makes the most sense for this experiment is because the color of the FeSCN2+ ion was blood red.

Using the yellow tube, which included everything but starch, as the blank, each group zeroed their spectrophotometer. This was done so that any absorbance observed depends only on the amount of starch present, not on any other reagents (buffer, IKI). To zero the spectrophotometer, the wavelength was first set at 580nm, using knob 3 (45). Next, the groups made sure that the light next to “transmittance” was lit, and the chamber to be tightly closed. Having the chamber empty & closed tightly provides reference for the darkest condition possible. Using knob 1, the transmittance was turned until it read 0.0 (45). Before the groups used their blank test tube to zero the spectrophotometer, each needed to wipe the tube with kimwipes to ensure a clean reading. Turning knob 2, each group was then instructed to zero the absorbance, 0.000. Upon removing the blank, each trial was inserted into the chamber (46). The

The dyes in the laboratory experiment are made of numerous colors, mainly red and blue, the spectra from each of the dyes corresponded to the wavelengths obtained from each of dye i.e. 620 nm for red and 450 nm for blue.

As far as thermal performance goes, both of these materials can provide it sufficiently for your skylight. Aluminium is best when the skylight is double glazed and is paired with the right glass. PVC is naturally insulating and will perform well regardless of the style of skylight.

This explains why in low lights, such as moonlight, everything appears gray. As Rainwater said “By definition, color includes all aspects of light except variations in time and space.” (98) So color and light go hand in hand with each other “The color you see depends on the intensity and wavelengths of the light that illuminates the object, on the wavelengths of light reflected or transmitted by the object, on the color of the surrounding objects, and on absorption or reflection by substances in the light path” (Rainwater 99) Hue, saturation and brightness refer to the aspects of color. “Hue is the color sensation by which you distinguish the different parts of the spectrum- red, blue, green, yellow, etc.” (Rainwater 101) Saturation appears as the degree of hue in a color. “It is the color sensation by which you distinguish a hue as being pale or rich, weak or strong.” (Rainwater 102) Another one, brightness “Brightness is the primary visual sensation by which you detect the presence of light. It is associated with the quantity of the light and the intensity of the visual sensation.” (Rainwater 103) These refer to just some of the terms associated with color and the human

Humans have three cone cells that are extremely sensitive to Red, (620-700nm), Green (490-570nm) and Blue (450-495nm) wavelengths of light. Although these three cones are most sensitive to these wavelengths, they are still sensitive to the remaining wavelengths of visible light between 400-700nm. When a light with a wavelength of 600nm is transmitted through the retina, the Red and Green cones capture, sense and signal the brain that orange light is observed. In this case the Red and Green cones absorb light but the Green cones are less sensitive. Also, the Blue cones don’t absorb much light and are not sensitive

Humankind has gone through many ages including the Stone Age, Bronze Age, Iron Age, the Middle ages, Machine age, and the period we are in today. Many valid arguments for what period we are in today including the Big Data Age, Social Age, or even Information Age. However, I think a valid argument can also be made for the Glass Age. Throughout this course we have covered many topics while using a wide variety of equipment and technology all made possible through the advancements of glass. From window panes absorbing UV radiation, microscope lenses or eye glasses, to the fiberoptic cable that keeps us in an information age. Todays world would not be possible without glass.

Copper will do just fine. Obviously fiber optics will be the better choice, but “beggars can’t be choosers”

In this experiment, paper chromatography was used to determine what pigments were present in spinach extract. From this experiment, we can see that four different types of pigments are present in the spinach extract used, the following are those pigments: chlorophyll a, chlorophyll b, beta carotene, and xanthophyll. The absorption and reflection of these pigments all revolve around the basis of the electromagnetic spectrum. The form of electromagnetic radiation is released as light and overall it is a type of energy that travels in waves. Going back to the spectrum itself, all the different types of electromagnetic radiation combine to form the electromagnetic spectrum, which tells us which colors can be absorbed and/or reflected. Each wave
