24.7 Resolution and the Rayleigh Criterion Raleigh Criterion: Effect of Star Separation Explanation: The video shows  light coming from two distant stars, passing through a circular aperture, and producing an image on a screen. As discussed in Section 24.7, the images on the screen are better resolved when the angular separation is larger. The video ends with an image of the limiting angle for Raleigh resolution.   Source: Samantha Shoemake and John T.
