Hello, I'm trying to set up an experiment to measure the distance between tracks in a CD, using only 3 items.
I can only use a cardboard box, a ruler, and a laser pointer, and I will be using a double slit.
So I'm thinking I will cut two slits in the carboard box, place it in front of the laser, place the cd behind that, and shine the laser through the slits, off of the cd and reflect them onto the wall. Then I would use d (sinθ) = mλ to calculate for d.
Does this seem logical?
Thanks for the input.
