  2. The Third Wave (experiment) - Wikipedia

    en.wikipedia.org/wiki/The_Third_Wave_(experiment)

    "The Pride of Lakewood", a 2010 episode of children's animated series Arthur, was loosely based on the Third Wave experiment. In it, students who form a community pride group become fascistic. In 2010, Jones staged a musical called The Wave, written with some of the students in the class. [12]

  3. Diffraction from slits - Wikipedia

    en.wikipedia.org/wiki/Diffraction_from_slits

    The mathematical representation of a radial wave is given by = ⁡ (+) / where =, is the wavelength, is frequency of the wave and is the phase of the wave at the slits at time t = 0. The wave at a screen some distance away from the plane of the slits is given by the sum of the waves emanating from each of the slits.

  4. Melde's experiment - Wikipedia

    en.wikipedia.org/wiki/Melde's_experiment

    A model of Melde's experiment: an electric vibrator connected to a cable drives a pulley that suspends a mass that causes tension in the cable. Melde's experiment is a scientific experiment carried out in 1859 by the German physicist Franz Melde on the standing waves produced in a tense cable originally set oscillating by a tuning fork , later ...

  5. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    [3] [4] [5] Thomas Young's experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that the Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment [6] or Young's ...

  6. Probability amplitude - Wikipedia

    en.wikipedia.org/wiki/Probability_amplitude

    A wave function for a single electron on 5d atomic orbital of a hydrogen atom. The solid body shows the places where the electron's probability density is above a certain value (here 0.02 nm −3): this is calculated from the probability amplitude. The hue on the colored surface shows the complex phase of the wave function.

  7. Phase problem - Wikipedia

    en.wikipedia.org/wiki/Phase_problem

    In physics, the phase problem is the problem of loss of information concerning the phase that can occur when making a physical measurement. The name comes from the field of X-ray crystallography , where the phase problem has to be solved for the determination of a structure from diffraction data. [ 1 ]

  8. Franz Melde - Wikipedia

    en.wikipedia.org/wiki/Franz_Melde

    Standing waves, in which each immobile point represents a node. Franz Emil Melde (March 11, 1832 in Großenlüder near Fulda – March 17, 1901 in Marburg) was a German physicist and professor.

  9. Phase velocity - Wikipedia

    en.wikipedia.org/wiki/Phase_velocity

    Propagation of a wave packet demonstrating a phase velocity greater than the group velocity. This shows a wave with the group velocity and phase velocity going in different directions. The group velocity is positive, while the phase velocity is negative. [1] The phase velocity of a wave is the rate at which the wave propagates in any medium.
