**Mark**, Tuesday, July 27, 2010 at 7:58pmOkay. So first for part b I know the formula I'm going to need is v=wr. That will relate the linear speed to the angular speed and we are given the radius. I'm still a little stuck though on the angular speed. I found the circumference of the wheel to be 10pi cm, and the space in between each slit to equal pi/50 cm (not sureif this is helpful). So should I find out the time it takes each light particle to get to the next slot using the speed of light given, then divide the distance between each slot byt hat time to get the angular speed?
