← ScienceWhich outcome occurs when a spatially incoherent light source illuminates double slits?
A)Fringes disappear from the pattern✓
B)Higher visibility interference fringes form
C)Central bright fringe intensity increases
D)Diffraction minima become less defined
💡 Explanation
Spatially incoherent light results in the overlap of many independent interference patterns with random phases; because the path difference varies randomly, the fringes wash out due to destructive interference, therefore fringes disappear rather than form because incoherent light lacks fixed phase relationships.
