I'm doing a physics project on diffraction, where you use a laser and reflect 
the laser light onto a screen and measure the distance between the orders and 
can work out the track spacing using n-lamda = d sin theta. I then need to work 
out the track length of the whole CD and there is supposed to be a formula can 
you help??
thankyou
