[edit] Summary
Description |
Shown above are longitudinal acoustic phonons in a 1D-lattice. These six different phonons have identical amplitudes (y) but have wavelengths of the following increments of molecular pitch: λ = 2, 2.4, 3, 4, 6, and 12. Their ratios of frequency (ωk) over their natural frequency (ω) range from 0.52 to 2.00 ωk/ω.

This is a compressed version of the Image:1D normal modes.gif phonon animation on Wikipedia Commons that was originally created by Régis Lachaume and freely licensed. The original was 6,039,343 bytes and required long-duration downloads for any article which included it. This version is 4.7% the size of the original and loads much faster. This version also has an interframe delay of 40 ms (v.s. the original’s 100 ms). Including processing time for each frame, this version runs at a frame rate of about 20–22.5 Hz on a typical computer, which yields a more fluid motion. Greg L 00:41, 4 October 2006 (UTC).
