Science Buddies: "Ask an Expert"

hey i really need some help for my project. I did all of the experiment and recorded the data, but i don't understand what the data tells me and how it realates to the track spacing? In other words, how do the reflection points measure how much track space there is? My final Draft is due in Two days. please hurry!

HI,

Heere is the Science Buddies project writeup of your experiment:

The theory is explained in the Introduction section, and the Bibliography section has links to demos and tutorials. Pay particular attention to the third one:

If these do not make sense to you, post back with your detailed questions and we will try to help you understand the tough parts.

Good luck!
