In the Young's double slit experiment using a monochromatic light of wavelength $\lambda$, the path difference ( in terms of an integer $n$ ) corresponding to any point having half the peak intensity is

• A

  $\left(2\text{n}+1\right)\frac{\lambda }{2}$
• Correct answer
  B

  $\left(2\text{n}+1\right)\frac{\lambda }{4}$
• C

  $\left(2\text{n}+1\right)\frac{\lambda }{8}$
• D

  $\left(2\text{n}+1\right)\frac{\lambda }{16}$

Hence, the correct answer is option: 'B'.
