Poisson–Arago Spot

អំពីការពិសោធន៍និម្មិតនេះ

Scalar Fresnel diffraction from an opaque circular disk approximates the sphere’s silhouette. The incident wave is monochromatic and planar. The on-axis intensity equals the unobstructed intensity I₀. Screen brightness uses fixed exposure; refraction and reflection are omitted.

អ្វីដែលសិស្សអាចស្វែងរកបាន

  • Can a shadow have a bright centre? Change the sphere radius, wavelength and screen distance.
  • Light bending around an opaque sphere creates a bright point at the centre of its shadow. Switch to geometric rays to compare.
