| Find the opening size
A yellow He-Ne laser with λ = 594 nm is lighting on a circular opening. There's a screen 5.0 m away with a bending pattern. The fifth dark ring (starting from centrum) has the diameter 10.5 cm. Determine the size of the circular opening.
I think that I might need to use the formula D*sin(x) = k*λ to solve for D, but other than that I'm unsure how to go about.
Thanks
