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

$A$ screen is placed at a distance $50\,cm$ from a single slit,which is illuminated with light of wavelength $690\,nm$. If the distance between the first and third minima is $3.00\,mm$,what is the width of the slit (in $,mm$)?

In a single slit diffraction pattern,identify the incorrect statement from the following.

$A$ beam of light having wavelength $5400 \text{ Å}$ from a distant source falls on a single slit $0.96 \text{ mm}$ wide and the resultant diffraction pattern is observed on a screen $2 \text{ m}$ away. What is the distance between the first dark fringe on either side of the central bright fringe (in $\text{mm}$)?

The diffraction of light starts from an obstacle (edge). It depends on ...

In the case of Fraunhofer diffraction at a single slit,which of the following statements correctly describes the diffraction pattern on the screen?
