The phenomenon of diffraction can be exhibited by

In the diffraction due to a single slit,the central fringe ...

In a diffraction experiment from a single slit, the angular width of the central maxima does $NOT$ depend upon

Obtain the formulas for the angular width and linear width of the central maximum in a single-slit diffraction experiment.

In Fraunhofer diffraction due to a single slit,the direction of the second secondary maximum is given by ....... ($a$ is the width of the slit).

$A$ screen is placed $0.5 \,m$ away from a single slit which is illuminated by a monochromatic light of wavelength $6000 \text{ Å}$. If the distance between the first and third minima in the diffraction pattern on the screen is $3 \,mm$, then the slit width is: (in $\,mm$)
