Is it possible to create the double slit experiment at home?
iii) I’m finding home double-slit to be very hard. I didn’t know black electrical tape was partially translucent to laser pointers! So far I’ve succeeded in producing a fuzzy patck on the wall. Ideally, I’d like to scrap the laser pointer and do a pinhole source, but some people may have laser pointers for their pets (found at a pet shop)! Reading Jimbo07’s comment on the speed of light thread motivated me into replicating Young’s famous experiment. It took me about two hours to get it working. You need: -A laser pointer -card -cardboard, or plasticard (sheet styrene) -a screen or white wall -a pin -a pair of scissors or a knife -white glue Step 1: The pinhole light source. Use the pin to punch a hole through a piece of plasticard (available from any craft shop. If you don’thave any, thick cardboard should do the trick). Shine the laser through the pinhole onto the screen. This should produce the distinctive one slit diffraction pattern. Step 2: The double-slit. cut a one squareb inch
