  1. Yeah I remember doing this in physics class with lasers through slits! Since we used a red laser, we only had 1 wavelength, so all the spots were truly spots. We could even go out and measure the distance between the slit an the wall, and the distance between the dots and calculate the wavelength I believe. We also tested light polarisation that day, and I learned how 3D glasses work. Enioy science class kids, it can be really fun!
