Predict

Predict

If you keep magnification fixed but increase aperture, what changes: brightness, resolution, or both?

Play

Play

  1. Compare two apertures and note what details become distinguishable.
  2. Try to separate a close pair; record the threshold where it becomes possible.
  3. Compare the effect of changing magnification vs changing aperture.
Explain

Explain

Explain why resolution is limited and why aperture matters for detail.

Learning goals

  • Distinguish magnification from resolution.
  • Explain how aperture affects the ability to separate close objects.
  • Connect resolution limits to diffraction qualitatively.

Misconceptions targeted

  • More magnification always shows more detail.

Model notes

  • Diffraction-limited scaling: $\\theta_\\mathrm{diff} \\approx 1.22\\,\\lambda/D$ (converted to arcseconds for readouts).
  • Atmosphere (toy model): seeing can dominate over diffraction; AO reduces the seeing contribution in the demo.
  • The Copy Results export includes diffraction limit, effective resolution, and resolved/marginal/unresolved status (with explicit units).

About this demo

This demo shows how telescope resolution depends on wavelength and aperture, and how atmospheric seeing can blur images from the ground.
