Question

For a diffraction from a single slit, the intensity of the central point is

• A. Infinite
• B. finite and same magnitude as the surrounding maxima
• C. finite but much larger than the surrounding maxima
• D. finite and substantially smaller than the surrounding maxima
• E. Zero

Answer 1

Answer: (C)

In single slit diffraction pattern, the intensity of the central point or fringe is finite and it is always much larger than the surrounding secondary maxima
