A) 0.08 rad
B) 0.06 rad
C) 0.12 rad
D) 0.15 rad
E) 0.012 rad
Correct Answer: E
Solution :
Given single slit of width \[d=0.1\text{ }mm\] \[d=0.1\times {{10}^{-3}}m\] or \[d=1\times {{10}^{-4}}m\] Light of wavelength\[\lambda =6000{\AA}\] or \[\lambda =6\times {{10}^{-7}}m\] The angle of diffraction \[\theta =\frac{n\lambda }{d}\] \[\theta =\frac{2\times 6\times {{10}^{-7}}}{1\times {{10}^{-4}}}\] \[\theta =12\times {{10}^{-3}}\] \[\theta =0.012rad\]
