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

Options

A. no diffraction pattern
B. that the central maxima narrower
C. less number of fringes
D. more number of fringes.

Answer

A

Explanation

For diffraction, size of the aperture of the obstacle must be comparable with the wavelength of light. Due to smallness of wavelength, X-rays can not be diffracted by ordinary apertures or obstacles.
