Density Plots
[edit]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
[edit]The wave near the slits (0.15mm across by 0.075mm high). This is looking down at the the wave at t=0.
![Two-Slit Diffraction (close up)](https://upload.wikimedia.org/wikipedia/commons/thumb/9/93/Two_Slit_Interference%2C_800nm_wl%2C_0.1mm_d%2C_close_up.png/500px-Two_Slit_Interference%2C_800nm_wl%2C_0.1mm_d%2C_close_up.png)
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:
