Question

In a single-slit diffraction experiment, monochromatic light of wavelength is sent through a narrow slit and produces a pattern of bright and dark fringes on a screen. The first dark fringe appears at an angle theta from the center of the pattern.


Rank the following single-slit diffraction experiments in order of the width of the slit, from largest to smallest.

A. l=400nm , q=0.002 radian
B l=600nm , q=0.004 radian
C l=400nm , q=0.004 radian
D l=600nm , q=0.002 radian

explain step by step will rate saver.

Explanation / Answer

its D A C B get it from equation a*sin(angle)=wave the l is wave and angle is q so solve for a because a is the unknown size of the slit
