longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students would get into a group. 2. A Slinky would be spread along a table or along the floor and set up as it shows on the

within the electromagnetic spectrum. Radio waves can be defined by their frequency (in hertz‚ after Heinich Hertz ‚ who first produced radio waves electronically)‚ which is number of times they pass through a complete cycle per second; or by their wavelength‚ which is determined by the distance (by meters) that is traveled from the crest of one wave to the crest of the next. Radio frequencies are measured in units called kilohertz‚ megahertz‚ and gigahertz. (1 kilohertz = 1000 hertz : 1 megahertz

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

interference‚ as in Young’s slits‚ but with a large number of sources‚ the process be labelled diffraction. While diffraction occurs whenever propagating waves encounter such changes‚ its effects are generally most pronounced for waves whose wavelength is roughly similar to the dimensions of the diffracting objects. If the obstructing object provides multiple‚ closely spaced openings‚ a complex pattern of varying intensity can result. This is due to the superposition‚ or interference‚ of different

Quantum mechanics is one of the major revolutions in 20th century Physics. It is probably the closest science has come to a fundamental description of the underlying nature of reality. And yet it is totally bizarre—it flies in the face of all our intuition and common sense. It sounds more like science fiction‚ or a poorly written fantasy‚ than notions which serious scientists would entertain. In this paper‚ we attempt to explain some of these fantastic notions for the layman. This paper comes with
