$Wave frequencies passing a grating This video shows a simulation of a transmissive grating on a glass plate that sends different wave frequencies in different angular directions. In the second part it show how it also does this if the incoming wave is a linear sum of 3 different frequencies. Thereby it performs a Fourier transform on the incoming wave signal (time domain) to intensity in an angular direction (a spectrum in the frequency domain) It was reuploaded because the original version contained an annoying error in the frequency indices. The Python code used for the wave simulation can be found on the @DiffractionLimited channel$ $Telescope Resolution vs. Aperture and Wavelength Discussion about of the fundamental limitations imposed by aperture and wavelength on the maximum sharpness of a telescope. By discussing the energy mechanisms behind diffraction, I try to explain why this relationship exists. In the last part I discuss the implications for the recently launched James Webb telescope. Contents: 0:00 Intro 2:43 Short experiment with aperture 4:47 About angular resolution 7:44 Resolution comparison of 3 different telescopes 10:13 Diffraction phenomena explained using energy as a basis 14:08 Experiment showing edge diffraction in real aperture 17:14 The James Web resolution explained using aperture and wavelength More about the background of the microscope experiment shown here is explained in this video: https://www.youtube.com/watch?v=TshYfYIxR9E Electromagnetic theory taken from Fundamental University Physics, Part 2: Electromagnetism by Marcelo Alonso and Edward J. Finn More information on the application of small telescopes can be found on the oresat.org website: http://oresat.org Aberrator 3.0 is a software program written by Cor Berrevoets to simulate star-images in different telescopes.
