Basic Notion of Double-slit interference
The Difference between single-slit and double-slit:
The coefficient m
Single:
Constructive: m=0,1.5,2.5...
Destructive: m=1,2,3...
Double:
Constructive: m=0,1,2,3...
Destructive: m=0.5,1.5,2.5...
The coefficient m
Single:
Constructive: m=0,1.5,2.5...
Destructive: m=1,2,3...
Double:
Constructive: m=0,1,2,3...
Destructive: m=0.5,1.5,2.5...
Wave lab experiment
Wave lab: Diffraction lab
Equipment:
Laser(s)/Any source of light that can emit parallel rays of light
Usable wall and double slit
Metric Ruler
Procedure/purpose: Shining the laser through the slits and measure the necessary constants along with the lengths between fringes to derive the wavelength of the light.
Similarly, a single-slit interference lab can be created.

Chart for Graphing & Calculating the Wavelength
In this case, such a chart could be used because the equation for the length between fringes contains a constant value--the wavelength.
