A) That the central maxima is narrower
B) No diffraction pattern
C) More number of fringes
D) Less number of fringes
Correct Answer: B
Solution :
Diffraction is obtained when the slit width is of the order of wavelength of EM waves (or light). Here wavelength of X-rays\[(1-100\,\,{\AA})\]is very-very lesser than slit width (0.6 mm). Therefore no diffraction pattern will be observed.
