Good evening to all you genius people out there, I've been racking my brains for the past 10 minutes and cant come up with anything.(adsbygoogle = window.adsbygoogle || []).push({});

The exact wording of the question:

Describe how you could use light of a known wavelength to find the distance between two slits.

I thought of using distance = wavelength/ sin(theta). But then I realized I'm not given the angle. Got any suggestions for this predicament?
