A) distance between slit and source
B) wavelength of light used
C) width of the slit
D) frequency of light used
Correct Answer: A
Solution :
The following ray diagram shows the single slit diffraction pattern. This is guided by Huygens principle. The properties of the system are wholly dependent on the ratio \[\frac{\lambda }{W}\] where\[\lambda \]is wavelength and W the width of slit. Angular width \[=\frac{\lambda }{W}\] Hence, angular width does not depend upon the distance between slit and source.You need to login to perform this action.
