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 :
Wavelength of x-rays \[(1-100\overset{\text{o}}{\mathop{\text{A}}}\,)\]<< width of the slit (0.6 mm) No diffraction pattern will be observed. When width of slit is of the order of wavelength of light, diffraction is obtained.You need to login to perform this action.
