- Relevant Equations:
- angle=wavelength/(2a)

The destructive interference equation for small angles is angle=wavelength/(2a), where a is the width. I assume it means destructive interference since its talking about areas where no light is present.

Using the equation after changing degrees into radians I get the answer of 2491 nm when the answer shoould be 9982 nm. the answer is approx. 4 times as large. Where am I going wrong here?
