Single-Slit Diffraction

Introduction
The Single-Slit diffraction experiment is amazing !

“The Action Lab” has conducted the experiment using an crescent wrench with 2 razor blades and a laser pointer: https://youtu.be/9HfUalNXPrk

This 3D model provides a magnetic holder for two razor blades to form an adjustable single slit and a holder for a laser pointer.

Let's repeat the experiment !

Materials
1 x laser pointer (e.g. LASERFUCHS Punktlaser Lasermodul rot 650nm 1mW)
2 x razor blades (e.g. Wilkinson Sword Classic Vintage Edition / Wilkonson Classic Shave Double Edge Blades )
4 x magnets (5 mm diameter, 1 mm height)
1 x screw 3x20 mm, hex head
1 x nut M3
glue

Safety
Read and follow the safety instructions of your laser pointer.

NEVER put yourself into any position where your eyes approach the axis of the laser beam (even with eye protection on). Keep beam paths below or above standing or siting eye level. Do not direct them towards other people or animals.
