//to calculate ratio of intensity
//I1/I2=1/25
//formula is a1/a2=sqrt(I1/I2)=1/5
a2=5 //a2=5*a1
a1=1
I=((1+5)^2)/((1-5)^2)
disp("ratio of intensity at the maxima and minima in the interference pattern is Imax/Imin=((a1+a2)^2)/((a1-a2)^2)="+string(((a1+a2)^2)/((a1-a2)^2))+"unitless")
//answer is given in terms of ratio
