Question
Yallow light is used in a sinle slit diffraction experiment with slit width of 0.6 mm. If yellow light is replaced by X-rays, then the observer pattern will reveal
Options
A.that the central maximum is narrower
B.more number of fringed
C.less number of fringes
D.no diffraction pattern
Solution
Diffraction is obtained when the slit width is of the order of wavelength of light (or any electromagnetic wave) used. Here, wavelength of X-rays (1-100 
) << slit width
(0.6 mm). Therefore, no diffraction pattern will be observed.
) << slit width (0.6 mm). Therefore, no diffraction pattern will be observed.
