Light of wavelength λ is emitted by two point sources. The light passes through a circular aperture of diameter b and is received by an observer. The angular separation of the sources from the observer’s position is θ. The sources are not resolved by the observer. Which of the following mathematical relationships applies?

A. \(\theta  < 1.22\frac{\lambda }{b}\)

B. \(\theta  > 1.22\frac{\lambda }{b}\)

C. \(\theta  = 1.22\frac{\lambda }{b}\)

D. \(\theta  = \frac{\lambda }{b}\)

A
