← ScienceWhich intensity pattern results when coherent light encounters diffraction?
A)Series of alternating bright fringes✓
B)Uniformly illuminated circular Airy disk
C)Continuous blurring diminishing resolution
D)Random speckle with no order
💡 Explanation
Alternating fringes appear, because constructive and destructive interference arises from diffraction. Diffraction splits the light in multiple directions that can then interact via wave interference, therefore fringes form, rather than a disk or blur, which does not require division.
