lol....it's ok

substitute for different phase difference...in the first case phase diff is pi, followed by 3pi,5pi,7pi ...like i said for destructive interference, it has to be an odd multiple of pi..

substitute these in the eqn to get wavelength.. phase diff= 2pi/ lambda  X path diff
for phase diff     wavelength/lambda
      pi                   56
      3pi                 18.7
      5pi                 11.2
      7pi                  8

hope ur getting it

dodo:
sorry i get the pi=56 but the 3pi is not coming out could u plz wirte it in numbers because is not coming
thx really ur so helpful :) :) :)

no problem

for 3pi

wavelength= 2pi/3pi X 28
               = 2/3 X 28
               =18.7

got it?
