laserland Single Slit Double Slits Combination Trellis Design Optics Elements Interference Diffraction Grating Sheet Optical Physical Experiment Kit

Hasta en la cocina de la casa funciona el experimento. 100% recomendado!

it works as expected. it might worth buying another color of laser for educational purposes (ie, to demonstrate it using 2 . thanks. different wavelengths)

I measured laser wavelength in course of double slit experiment. While 0.3mm slit gave correct results with an average error 1.7%, 0.2mm slit gave consistently wrong results. Although it would be difficult to confirm, I suspect the slit is labelled wrongly on a diaphragm and is actually 0.25mm wide. Then average error would be then 1.89%, not 18.5%, consistent with other measurments. With both slits I did 9 measurments, distances from 1m to 5m using 635nm laser provided in the set.

Ojala que las dobles rendijas e pudieran imprimir en metal o en vidrio para utilizar más potencia.

I bought for my kid, it’s a nice demo for optics experiments, good quality
