//Variable declaration
theta=45*%pi/180 //glancing angle(radian)
d=275 //interplanar spacing(pm)
n1=3
n2=4
//Calculation
lamda=2*d*sin(theta) //wavelength(pm)
lamda1=lamda/n1 //wavelength for n=3
lamda2=lamda/n2 //wavelength for n=4
//Result
printf("\n wavelength for n=3 is %0.0f pm and for n=4 is %0.2f pm",lamda1,lamda2)
printf("\n answer for wavelength for n=4 given in the book varies due to rounding off errors")
