This resource provides a nice way to simulate physics and astronomy phenomena. A category from a menu is selected to browse the catalogue of animations by category. Most animations are 512 by 384 pixel avi files and are generally several megabytes long. Small screenshots are provided, and the user may view the animation in three ways: direct link to the media file, and two versions of a link to a page with the animation embeded in a web page with a brief comment on the animation. There are two methods used to embed the animation because not all work equally well with any one method.

Interference of Harmonic Waves (varying phase)

REA Catalogado

Average rating: 

2

Promedio: 2 (1 reseña)

A very pretty animation of the interference of transversal harmonic waves, with the same amplitude. It is clear that when the phase difference between waves is 0 or multiples of "2pi" radians (360°) the interference is totally constructive, and when it is "pi/2" radians (180°) it becomes totally destructive.
