//Variable declaration
lamda1=5016*10**-8 //wavelength(cm)
lamda2=5048*10**-8 //difference in wavelength(cm)
k=2 //order
n=15000 //number of lines/inch
//Calculation
e=2.54/n
theta1=asin(2*lamda1/e)*180/%pi //angle for 1st wavelength(degrees)
theta2=asin(2*lamda2/e)*180/%pi //angle for 2nd wavelength(degrees)
theta=int(60*(theta2-theta1)) //angle of separation(minutes)
//Result
printf("\n angle of separation is %0.3f minutes",theta)
