students viz. Harleen Kaur‚ Rutvi Patel and Sandhya‚ determining the wavelength of light from a laser using a double – slit slide. The laser was shone through the double – slit such that it projected interference pattern onto the paper screen. The experiment will be repeated three times varying the distance between the slit and the screen to understand the effective relationships. The expected wavelength of the laser light is 6.5 X 10-7‚ however‚ the value found of the wavelength is 7.56 X 10-7 with an error

D2 – Forced‚ Damped Vibrations with Rotating Out-of Balance Excitation (Norwood Apparatus) Introduction This lab report was aimed at investigating out-of-balance rotating masses in single degree of freedom systems‚ paying specific attention to obtaining plots of amplitude against angular velocity. This was done using a specific setup of apparatus (Detailed below) and our findings were plotted in the form of graphs and also‚ we investigated the experiment in a way which allowed

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

In Washington Irving’s “The Legend of Sleepy Hollow‚” readers follow Ichabod Crane from his fascination in mysteries to him becoming one. Being a schoolmaster‚ Crane travels around town and interacts with all types of civilians. The story is intensified with detailed descriptions of the diverse settings in town. These descriptions reflect Ichabod Crane’s way of life‚ his greediness‚ and his competition with Brom Bones. The portrayal of the schoolhouse in the story reflects Ichabod and how he is

Advice to Youth by Mark Twain (1835-1910) Being told I would be expected to talk here‚ I inquired what sort of talk I ought to make. They said it should be something suitable to youth--something didactic‚ instructive‚ or something in the nature of good advice. Very well. I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable.
