A) that the central maximum is narrower
B) more number of fringes
C) less number of fringes
D) no diffraction pattern
Correct Answer: D
Solution :
Diffraction is obtained when the slit width is of the order of wavelength of light (or any electromagnetic wave). Here, wavelength of X-rays\[(1-100{\AA})<<\]slit width (0.6 mm). Therefore, no diffraction pattern will be observed.
