(Solution) - An astronaut in orbit can just resolve two point sources -(2025 Original AI-Free Solution)
Paper Details
An astronaut in orbit can just resolve two point sources on the earth that are 75.0 m apart. Assume that the resolution is diffraction limited, and use Rayleigh's criterion. What is the astronaut's altitude above the earth? Treat her eye as a circular aperture with a diameter of 4.00mm (the diameter of her pupil), and take the wavelength of the light to be 500 nm.
