Paper Electron diffraction through a graphite film. Mark Raskin Skidmore College (11/14/14) Abstract: In this paper‚ the wave-like properties of electrons are discussed. We are trying to measure the inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents

The protagonist of “One’s a Heifer” goes on a quest to find his two lost calves. But the primary reason for taking this journey is to show his Aunt Ellen that he’s not a child anymore and is capable of succeeding. “I didn’t wave back” (54): this is the protagonist’s first attempt at adulthood‚ not waving goodbye to his aunt. Throughout his journey‚ the boy travels through “silent miles of prairie‚” “nagging winds‚” and deadly cold‚” yet he remains determined: “[I] choked my disappointment down and

Information‚ such as sound‚ is carried by systematically changing (modulating) some property of the radiated waves‚ such as their amplitude‚ frequency‚ phase‚ or pulse width. When radio waves strike an electrical conductor‚ the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. In November 1894 public demonstration at Town Hall of Kolkata‚ Jagadish Chandra Bose ignited gunpowder and rang

Doppler effect. The Doppler effect states that a change in frequency of a wave will occur for an observer that moves relative to the wave. This is seen in our everyday life‚ for example‚ when the siren of a police car or fire truck passes you‚ you are experiencing the Doppler effect. Key Variables Independent Variable: Original position of moving object (sound maker and sound recorder) Dependent Variable: Change in Wave Frequency (pitch of the note) Object moves at varying speeds of 5 mph

Electromagnetic Waves Although you might not know it you’re constantly surrounded by thousands of electromagnetic waves every day. Sunlight and x-rays are only two types of electromagnetic waves‚ other types are: radio wave‚ infrared rays‚ ultra-violet rays and gamma rays Nature of an electromagnetic wave Electric and magnetic fields are not made up of matter. An electromagnetic wave consists of an electric and magnetic field and doesn’t need a medium to exist. They are the regions through

Book Report I chose “The Shark And The Goldfish” by Jon Gordon for my book report. This book is about positive ways to thrive during waves of change and follows a goldfish named Gordy who washes out into the ocean. Gordy has always been taken care of and fed daily‚ but doesn’t know how to act or get food when he is in the ocean. He meets a nice shark named Sammy who teaches him how to find food and take care of himself. The story is a lesson for how you never know what life is going to throw

Mere static pictures do not do justice to Lissajous Figures. When the horizontal and vertical sine wave frequencies differ by a fixed amount‚ this is equivalent to constantly rotating the phase between them. The figure produced by this rotating phase appears to be a rotating 3D figure. In addition‚ as in 3D wireframe images‚ the figure can appear to rotate in either direction‚ depending on how your brain interprets it. It can also spontaneously reverse the direction of rotation. (In a real

The Polynesians were the masters of surfing and the best boards and beaches were open to only the upper-class and royalty of Hawaii. The working class citizens had to subside using boards made with unskilled hands‚ poor wood‚ and beaches with little wave activity. Fast-forward to the beginning of the 20th century‚ when Hawaiians living near Waikiki beach started to revive the ancient sport and brought it to North America. Slowly and quietly‚ surfing started a slow‚ steady climb until it took a tremendous

A microphone located at the opposite end of the rail detects two pulses of sound‚ one that travels through the air and a longitudinal wave that travels through the rail. (a) Which pulse reaches the microphone first? (b) Find the separation in time between the arrivals of the two pulses. 3.

that‚ I think she also slept with Wilson since unlike her husband he is not a coward. This was never actually stated but that’s how I inferred it. Also‚ moments before the gunshot‚ Macomber at one point looks back at her and waves‚ she‚ with the rifle besides her does not wave back. Even though love is a missing component in their relationship‚ she would of waved back if she was feeling in control of the situation but now that Macomber is fearless he has control.
