Here ψ is the angle between the path of the wave source and the direction of wave propagation (the wave vector k), and the circles represent wavefronts. Consider one of the phase circles of Fig.12.3 for a particular k, corresponding to the time t in the past, Fig.12.2. Its radius is QS, and the phase chevron side is the tangent PS to it.
The 2008 German film Die Welle transferred the experiment to a modern-day German classroom. The film received critical acclaim. "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.
The form comes with two worksheets, one to calculate exemptions, and another to calculate the effects of other income (second job, spouse's job). The bottom number in each worksheet is used to fill out two if the lines in the main W4 form. The main form is filed with the employer, and the worksheets are discarded or held by the employee.
Ron Jones (born 1941) is an American writer and formerly a teacher in Palo Alto, California.He is best known for his classroom exercise called "The Third Wave" and the book he wrote about the event, which inspired the made-for-TV movie The Wave and other works, including a theatrical film in 2008.
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.
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.
In-phase signals Out-of-phase signals Representation of phase comparison. [3] Left: the real part of a plane wave moving from top to bottom. Right: the same wave after a central section underwent a phase shift, for example, by passing through a glass of different thickness than the other parts.
The two colors show the phase or sign of the wave function in each region. Each picture is domain coloring of a ψ( x , y , z ) function which depends on the coordinates of one electron. To see the elongated shape of ψ( x , y , z ) 2 functions that show probability density more directly, see pictures of d-orbitals below.
