Single-slit diffraction is characterized by
A) narrowing of diffraction pattern as slit width is reduced.
B) a distance between fringes which is independent of wavelength.
C) rapid decrease in intensity of higher order fringes.
D) decreasing angular separation of fringes as the order (m) increases.

Question

Quizplus · Accepted Answer

Single-slit diffraction results in a central maximum that is much brighter than the subsequent maxima, with the intensity of these higher order fringes rapidly decreasing as one moves away from the center. This is due to the constructive and destructive interference of light waves passing through different parts of the slit.
