🔬 3D Wave Optics Optical Bench: Laser, Slit Plate and Screen Interference and Diffraction Lab

3D optical bench with a laser, N-slit card and sliding screen: double-slit and single-slit diffraction I = I0 cos^2(pi d sin(theta)/lambda) sinc^2(pi a sin(theta)/lambda), fringe spacing lambda L / d, white light and four numerical checks.
