#### Answer:

I found

#### Explanation:

I suppose here I am dealing with the Raileigh Criterion that tells us the minimum angular (in radians) separation between two object (emitting light of wavelength

We have for the first wavelength:

so that

For the second wavelengrt we have then a angular separation of:
