Homework Statement
Look at the Moire pattern in "Oppgave 5" (assignment 5) in the attached pdf file. The Moire pattern you see is supposed to represent the interference between two plane EM waves whose directional ##\vec{k}## vectors form an angle ##\theta## with each other.
Anyway, the main question is: "What is the angle ##\theta## between the patterns if the distance between the interference-strips is ##\Lambda = 2mm## and the wavelength of the light is ##\lambda = 550nm##.
Homework Equations
The Attempt at a Solution
According to the solutions manual, the distance between the interference-strips is given by ##\Delta \vec{k} = \vec{k_2} - \vec{k_1} ##
I do not understand how this is possible. Can somebody explain? This is the only thing I struggle with understanding.
