Plotting Intensity in Airy Pattern of Telescope - 1D

AI Thread Summary
To derive an equation for the intensity of the Airy pattern in a telescope, one must consider the telescope's aperture diameter and the wavelength of light being observed. The intensity distribution can be modeled using the sinc function, which relates to the diffraction pattern produced by a circular aperture. The goal is to plot intensity against the angle from the normal in one dimension, resembling the provided Airy pattern visual. Resources like Wikipedia offer useful overviews and equations for further understanding. This approach allows for accurate representation of the diffraction effects in telescope observations.

How would I come up with an equation (in one dimention), for the airy pattern of a telescope with a given diameter observing at a given wavelength? something that looks like this

I want to be able to plot Intensity in the image versus the angle from the normal, in one dimension.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
