## Physics

At the moment (Oct 2007) the next three SVGs do not render correctly, as they use the Inkscape blur feature which is not supported. However, hopefully it will be soon.

## Sounds

### DTMF

### Unwin's Construction of an Involute Spur Gear

Unwin's Construction is a method of drawing a close approximation to an involute gear tooth. There are 8 images in the series and a complete description of the method can be found on the page Unwin's Construction.

## Diffraction

### Density Plots

These density plots are highly detailed and need to be veiwed at full resolution for best effect. The images here are half-size. The wavlegnth is 800nm, and the slit separation is 0.1mm.

#### Two Slits

The wave near the slits (0.15mm across by 0.075mm high). This is looking down at the the wave at t=0.

This the same area, but averaged over a full cycle, to reveal the finging pattern

Further out (200mm across by 5 metres high). There are a lot of distortion and false patterns due to moiré and beat frequencies between the wave's frequency and the pixel/sampling frequency of the image/plotting.

Averaging over a full cycle reveals the simple fringe structure:
