**Diffraction and Circular Apertures in Astronomy**Diffraction due to a circular aperture is critical in astronomy. Telescopes with circular apertures of finite size produce diffraction patterns rather than point images of stars. Two distinct points are considered just resolved when the center of one point's diffraction pattern is in the first dark ring of the other. This concept of resolution is known as Rayleigh's criterion.For example, consider a telescope with an aperture diameter of 1.02 meters.**Task: Calculating the Angular Radius (θ₁)**Determine the angular radius θ₁ of the first dark ring for a point source imaged by this telescope.

The Rayleigh criterion provides a convenient way to describe the theoretical resolution (e.g. an ability to distinguish two bright objects ) of an optical system. The criterion states that two small bright sources of light can be resolved if the first diffraction minimum of the image of one source point just coincides with of further apart then the first maximum of another (see figure below). A converging lens, 31.5 mm in diameter, is used to form images of distant objects. Considering the diffraction by the lens, what angular separation must two distant point objects have in order to satisfy Rayleigh's criterion? Assume that the wavelength of the light from the distant objects is 516 nm. Provide your answer in millidegrees (mdeg).
