Unfortunately, this gives us absurd values for the necessary length of the optical path; for R to be plausibly small, L quickly approaches similar orders of magnitude. This approach is therefore invalid.

If we use the double-slit approach, treating the diamond as the spacing between the slits, the slits become arbitrarily large. Under this approximation,
If we use the double-slit approach, treating the width D of the diamond as the spacing between the slits, the size B of the slits becomes arbitrarily large. Under this approximation,
<math>I(\theta) = 4I\frac{\sin^2(\beta)}{beta}\cos^2(\alpha)</math>
where
<math> \alpha = \frac{kD}{2}\sin(\theta)</math>
and
<math> \beta = \frac{kB}{2}\sin(\theta)</math>
Again, this approximation fails, here because B can be arbitrarily large. Because of this, <math>\beta</math> can be arbitrarily large, and I goes to zero.
