Young's Double-Slit Experiment, Single Slit, with Holder Observation Board Red Light Source, Optics Elements, Optical Physical Experiment Kit, Interference Diffraction Grating Sheet 50 * 50mm

This is a low-cost way to very easily demonstrate the findings of the double-slit experiment. Its pretty inexpensively (aka cheaply) made, but there are no undue stresses, so it should last a long time.

It was as expected

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

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.

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

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

Very nice demonstration of optical effects of refraction and interference. The supports are not very stable. The laser is quite strong.
