In Dealing with the Diffraction Pattern of a Single Slit,we

Multiple Choice

In dealing with the diffraction pattern of a single slit,we are usually interested in the location of the first minimum in light intensity because

A) it is the only one that can be determined accurately.
B) it is the only one for which the small-angle approximation holds.
C) nearly all the light energy is contained in the central maximum.
D) it is the only one for which the location is directly proportional to the wavelength of the light.
E) it is the only one that can be described by Fraunhofer diffraction.
