Discussion The objective of this experiment is to apply spectroscopic methods to explore light emitted by different atoms heated in a flame; this is an introduction to the relationship between atomic line spectra and atomic structure. In part 1, we measured each color of light (from violet to yellow) and noticed that the wavelength increased as the spectroscope scale reading increased. The violet and blue lines were close together and so were the green and yellow lines. There was a gap between the violet/blue lines and the green/yellow lines. In plotting wavelength as a function of the spectroscope readings, we observed that the points formed a pretty straight line (indicating a linear relationship). We then took the linear least square fit of the data and used the equation of that line to determine the wavelengths in part 2. In part 2, the lines were spaced similarly to part 1. The violet and blue lines were close together and so were the green and yellow lines. There was a gap between the violet/blue lines and the green/yellow lines. The observed wavelength for blue was more close to its accepted wavelength than were the observed wavelengths for violet, green, and yellow. The % errors for the wavelength of each color were: violet=7.48%, blue=1.12%, green=7.45%, and yellow=11.40%. Most of our ninitial values were off (due to the observed wavelengths being off). They were violet: ninitial=7, blue: ninitial=4, green: ninitial=3, and yellow: ninitial=3. The actual values are violet: ninitial=6, blue: ninitial=5, green: ninitial=4, and yellow: ninitial=3. As such, the…
Marco Polo: An Italian merchant, Marco Polo set out to Asia with goals of establishing trade along the Silk Road. Other than accomplishing his goals of trading along the Silk Road, Polo also became the confidant of Mongol ruler Kublai Khan and wrote his travels in his journal which ultimately introduced much of Europe to Central Asia and Asia.
Henry the Navigator: Henry the Navigator was a Portuguese explorer who set out in hopes of finding a route to the rich spice trade in…

Exploration of “The Third Bank of the River”
The short story, “The Third Bank of the River” is by Joao Guimaraes Rosa. This story starts out by the father describing a boat that he is getting. It is made of mimosa wood, sturdy enough to last twenty or thirty years and just large enough for one person. When the mother heard of him getting the boat she acts is upset, she thinks the whole idea of him getting this boat is absurd. “Are you becoming a fisher or hunter?”…

I currently live with my dog at school and this past summer in New York City. We take two or three times a day. My dog is only a little more than one year old, but the bottom of his paws is already very rough and the vet said it is quite inevitable if he goes outside frequently. In addition, after every walk I clean his feet twice or three times with paper towels and hand sanitizer, since he comes onto my bed everyday…
Dickinson presents faith in a Certain Slant of Light.
In ‘There’s a Certain Slant of Light’ Dickinson uses the everyday yet illusory image of ‘light’ to express her doubt and confusion in her faith. However Dickinson overturns our conventional ideas of light being uplifting and edifying, by connecting it to ‘despair’ and oppression. Through this inversion Dickinson displays the restlessness that her preoccupation with faith causes her.
Although light is a visual image, it is immaterial and cannot…

In chapter one, the set is introduced and there is a significance of a rose bush near the prison door.
In chapter two we are introduced to Hester and her problem. We are also introduced to how Hester is a self-reliant woman and choses to accept her punishment of bearing the child.
In chapter three, Hester is put on trial and sees that her husband is not away, but that…
Age of Exploration
There are many positive and negative effects resulting from European exploration of the
The spread of Christianity through missionaries and cultural diffusion through the
Columbian Exchange are positive effects.
Spaniards treating the natives poorly and the spreading
of diseases are negative effects from the results of the European exploration.
The spread of Christianity was one of the many positive effects that was a result of the
European exploration. T…
Since the invention of the telescope by Galileo in 1607, mankind has been fascinated by the vast expanses of space- the great unknown. Long before this time ancient civilizations used the stars to navigate and predict future events. Archaic astronomy marked the rise of the curiosity of other existing worlds. The launching of Sputnik I by the Soviet Union in 1957 marked a pinnacle in human innovation as well as ignited a war that would change the course of mankind forever. The great…
The Age of Exploration
Throughout history and time, there has been many changes and revisions. With every fail
comes a new success and a new solution to a new problem. During a time period called the
Renaissance, people’s ideas have changed and they are looking towards new frontiers, this,
sparked the age of discovery and exploration. Today, we will be examining two major changes
which occurred in two different regions of the world as a result of the Age of Exploration. One
major change was…
examples of devices that need light sensors to function properly:
Car headlights that automatically turn on when it’s dark
Streetlights that automatically turn on when it gets dark
Outdoor security lights that turn on when someone walks by (but only at night)
Laptop displays that get brighter in well lit areas and dimmer in poorly lit areas
Cameras with automatic exposure settings
The first three examples in the list are automatic lighting, and they depend on ambient light sensors to distinguish…
