Rayleigh disk experiment
WebWhat it showsA telescope (with video output) at the front of the lecture hall is focused on two point light sources at the rear of the hall. Although the light sources are only 1/2 mm apart, they are readily resolved. The Rayleigh limit of resolution can be clearly shown by reducing the telescope aperture to the point where the two light sources can barely be … Web(Rayleigh, 1878) As with Rayleigh, the entirely intellectual exercise of studying this problem is likely fulfilling. The system represents one of many examples of dynamic surface tension fluid flows. The relatively simple experimental results give rise to a rigorous mathematical representation that robustly explains the underlying phenomena.
