Science Buddies: "Ask an Expert"

im rubbish with numbers so i am hopeing you can help:
im trying to scale up the double slit experiment,
a pool ball is 6cm in diameter, the rails of the pool table are 10cm thick, the cardboard used for the slits in the original experiment, look to be about 3mm thick. the sizes i have found for a photon are 10 to the minus 35 M to 10-32 meters, or another source gives a radius of 0.338* lambda.
so if we make a photon as big as a pool ball, how long will the pockets be ?
obvoiusly roughly will do.

Multiply any dimension you want to scale by : 6 cm / 1E-35 m or 6E-2/ 1E-35 or 6E33 in meters!

where E means "times 10 to the"

Note that the radius of the earth is 6.371 million meters or 6.371E6 m

Now: If you are interested in a large scale analog. Look up double slit water wave interference. Photons behave like waves in this case.
