Ripple article - Ripple physics waves liquid wavelengths surface tension forces density - What-Means.com In physics, ripples are surface waves on a liquid with wavelengths so short that the liquid's motion is governed almost entirely by surface tension forces. Ripple article - Ripple physics waves liquid wavelengths surface tension forces density- What-Means.com Unless otherwise specified, percent ripple is the ratio of the root mean square value of the ripple voltage to the absolute value of the total voltage. www.what-means.com /encyclopedia/Ripple   (127 words)

Physics 20 - Transmission, Reflection and Refraction of Waves The usual ripple tank experiments described in most physics textbooks are ideal in this section. The angle of incidence is equal to the angle of reflection. A decrease in the amplitude of a wave (as in a pulse travelling along a spring) indicates that energy is being dissipated, primarily due to frictional forces. www.sasked.gov.sk.ca /docs/physics/u2b12phy.html   (831 words)

Consciousness, Causality, Quantum Physics According to the conventional interpretation of quantum physics, however, not only is it impossible for us to measure a particle's position and momentum simultaneously with equal precision, a particle does not possess well-defined properties when it is not interacting with a measuring instrument. He admits that this theory is speculative, unvalidated, and may require new physics. It corresponds to what Bohm calls the implicate order, which can be thought of as a vast ocean of energy on which the physical, or explicate, world is just a ripple. ourworld.compuserve.com /homepages/dp5/jse.htm   (3609 words)

1999/12/01 04:42-Zala-[K-list] physics physical being is but a ripple of waves or a bundle of waves. This concept is the science of quantum physics. According to physics, the world around us is made of vibrating molecules, www.kundalini-gateway.org /klist/k1999b/k99b03240.html   (3609 words)

Session 1S - TFTR. An experiment was done in low-power DT plasmas to test the effect of the q(r) profile on the alpha particle ripple loss. A conjecture is offered that the second phenomenon involves currents that flow in the plasma scrape-off layer over part of their path and in the tokamak structure over the rest of the path (a toroidally non-symmetric form of \lq halo\rq\ currents). To test this theory, the plasma major radius was shifted inward in 80 msec from 2.6 m to 2.35 m and then shifted back out at the same rate after a delay of 320 msec. flux.aps.org /meetings/BAPSDPP96/abs/S80.html   (5967 words)

Sight and Sound - Scenario If your project is Sight and Sound in Nature, then I would expect your group to discuss the physics of waves (both light and sound waves), the physics of seeing and hearing, the physics of ray optics, and then the application of these physical concepts to how animals hear and see. When the Sight and Sound project was added to our repertoire, a ripple tank set-up with an accompanying wave generator was retrieved and prepared for use. Each Sight and Sound in Nature project group designed a step-by step procedure for each of the studies which they contracted to conduct and a discussion of their plan for analyzing and interpreting the data. www-ed.fnal.gov /help/97/sightsound/ssscen.html   (12701 words)

Inductor physics When current has reached its peak the inductor stops working until there is a disruption in current flow like in the case of ripple current or in the case of audio applications or power supplies. Well the philosophy behind the inductor is that flux lines can generate voltage, this is used to alter waveforms in circuits where there is a presents of ripple current. To flatten down the waveform you would use a device related to the inductor, known as the capacitor which is basically an inefficient battery that only holds a charge for fractions of a second but is perfect in an alternating DC circuit. www.compworks.faithweb.com /electronics/components/inductor001.html   (820 words)

Physics at Minnesota: If filter specifications call for a bandpass or bandstop filter with unequal ripple in each of the passbands or stopbands, design the filter as separate lowpass and highpass sections and cascade the two filters together. Now design a bandpass filter with a passband from 100 Hz to 200 Hz, less than 3 dB of ripple throughout the passband, and 30 dB stopbands 50 Hz out on both sides of the passband: initially develops a lowpass filter prototype by transforming the passband frequencies of the desired filter to 1 rad/sec (for low- and highpass filters) and to -1 and 1 rad/sec (for bandpass and bandstop filters). www.physics.umn.edu /support/doc/matlab/toolbox/signal/ellipord.html   (452 words)

The Physics Classroom In Unit 10, the value of a ripple tank in the study of water wave behavior was introduced and discussed. Interference principles were first introduced in Unit 10 of The Physics Classroom.

Shadows of Empyrean A ripple of æther, it poured from a hole in vastness itself that led to the Empyrean; Empyrean, that realm of light from which flows the translucent, fluidic æther that is energy itself, the nectar of heaven. The æther-shadows of the ships, mimicking the ships' presence in Empyrean, lurched forward at speeds in defiance of every rule of physics. A bright light glared in void, shivering with every breath of starwind and shuddering with every tug of gravity. www.pflug.com /kyle/shadows_of_empyrean.htm   (418 words)

Butterfly Effect One of the featurettes was a look at the quantum physics of the butterfly effect and the allure of time travel.

The Physics Classroom Interference principles were first introduced in Unit 10 of The Physics Classroom. In Unit 10, the value of a ripple tank in the study of water wave behavior was introduced and discussed. Whenever light constructively interferes (crest meets crest or trough meets trough), the two waves act to reinforce one another and to produce a "super light wave." On the other hand, whenever light destructively interferes (crest meets trough), the two waves act to destroy each other and produce no light wave. www.physicsclassroom.com /Class/light/U12L1b.html   (1558 words)

Waves and Wave-Like Motion The thought of waves often brings to mind a recent encounter at the baseball or football stadium when the crowd enthusiastically engaged in "doing the wave." When performed with reasonably good timing, a noticeable ripple is produced which travels around the circular stadium or back and forth across a section of bleachers. We study the physics of waves because it provides a rich glimpse into the physical world which we seek to understand and describe as physicists. The waves are created by some form of a disturbance, such as a rock thrown into the water, a duck shaking its tail in the water or a boat moving through the water. www.glenbrook.k12.il.us /gbssci/phys/Class/waves/u10l1a.html   (1558 words)

David Bohm The quantum potential, the superquantum potential, the implicate order, and superimplicate orders are all names given to realms that are invisible to ordinary perception, yet for Bohm, they constitute the true structure of reality. Within physics, Bohm has demonstrated that one way to interpret the Schroedinger equation in quantum field theory is to introduce a wave-like information field called the superquantum potential, whose action transcends all of space in a timeless unity. The "particle" (explicate order) is merely a discontinuous ripple effect created by the effect of the superquantum potential on the field. portfolio.chez.tiscali.fr /NewFiles/bohm.html   (2680 words)

Rane Professional Audio Reference (P) Used as another name for group delay; however there are instances where they are not the same, for example systems exhibiting ripple in their phase vs. frequency characteristics. Physics The rate at which work is done, expressed as the amount of work per unit time, and measured in units such as the watt (1 joule per second, which equals the power dissipated (as heat) by 1 ohm of resistance when 1 ampere of current passes through it) and horsepower (equal to 745.7 watts). Propagation delay is caused most often in analog electronics by phase delay in filter networks, and in digital electronics by computational delay in microprocessors and DSP devices, as well as data conversion. www.rane.com /par-p.html   (7383 words)
