In a single slit experiment, the width of the slit is doubled. Which one of the following statements is correct?
- A The intensity and width of the central maximum are unaffected.
- B The intensity remains same and angular width becomes half.
- C The intensity and angular width both are doubled.
- D The intensity increases by a factor 4 and the angular width decreases by a factor of \(\frac{1}{2}\).
Answer & Solution
Correct Answer
(D) The intensity increases by a factor 4 and the angular width decreases by a factor of \(\frac{1}{2}\).
Step-by-step Solution
Detailed explanation
For single slit diffraction, Fringe width \(\mathrm{W}=\frac{\lambda \mathrm{D}}{\mathrm{d}}\) Also, \(I \propto D^2\)
