A diffraction grating is a periodically structure of subsequent most evenly spaced grating lines. Those grooves or opaque lines diffract the incident light depending on its periocity and microstructure.

Explanation:
dSin(theta)= n (lambda)
dSin(theta) is constant
n1 (lambda1) = n2 (lambda2)
2 (lambda1) = 3 (lambda2)
lambda1 / lambda2 = 3/2
