Yellow light is used in single slit diffraction experiment with slit width `0.6mm`. If yellow light is replaced by X-rays then the pattern will reveal

Options

A. That the central maxima is narrower
B. No diffraction pattern
C. More number of fringes
D. Less number of fringes

Answer

B

Explanation

Diffraction is obtained when the slit width is of the order of wavelength of light Wavelength of X –rays is much less than width of slit Hence, no diffraction will be observed
