Homework Statement
Calculate the grating constant, d, given that theta = 172.01167 degrees, and that lambda = 447.2 nanometers.
2. Homework Equations
d = mλ / sinθ
where m is an integer that refers to the order of diffraction
where λ is the wavelength
where d is the spacing between two slits
where θ is the angle observed
The Attempt at a Solution
I understand the equation, but given the fact I have two variables (being m and d) I am unsure of how to solve. How do I determine the order of diffraction?
