Answer:
Intensity formula,

I=Imax cos2 (δ)        δ=phase difference
 
for path difference of λ, phase difference = 2 π
 
For this intensity is given as
 
M=Imax cos2 (δ) =Imax cos2 (2π) = Imax  (1)
 
for path difference of  λ /3,  phase difference = (2 π)/3
 
I=Imax cos2 (δ) = Imax cos2 (2π/3)= Imax (1/4) = M/4
