APFIVE Gaussian Aperture Diffraction Pattern
A diffraction experiment uses a slit with a Gaussian-shaped opening (intensity varies as e^(-x²/a²) where a is a constant). Compared to a rectangular slit of width 2a, the Gaussian slit’s diffraction pattern will have:
A
No secondary maxima, only a Gaussian central maximum
B
A narrower central maximum with sharper edges
C
The same pattern but shifted in phase
D
More pronounced secondary maxima
