Find the slit separation of a double slit arrangement that will produce interference fringes 11.5 mrad apart on a distant screen with light of wavelength 471.0 nm.(adsbygoogle = window.adsbygoogle || []).push({});

tan(theta) = y/D

asin(theta) = p * wavelength

I know that I'm trying to solve for a, and that asin(theta) = 11.5, but I feel like I don't know enough information to solve the problem. Could someone point me in the right direction?
