Hi there, I was doing some past year paper of my coming exam...and I got the answers for the question too, but one part I'm totally blur and can't understand that well... well here goes all the questions and solution:

http://server3.uploadit.org/files/chickens-ans1.jpg
http://server2.uploadit.org/files/chickens-ans2.jpg
The part that I'm confused is with the part (b)...the answer given by both different book ... the solution seems...a little blur to me.
Unclear to me:
1. why "for the first time the two lights coincide, change in m = 1" ?
2. the long and madness working...i totally have no idea what is going on...
Anyone kind here could help me explain all the steps? I'm very blur... thanks in advance.
