Question

A resonance tube is resonated with tuning fork of frequency $256Hz$. If the length of resonating air columns are $32cm$ and $100cm$, then end correction will be

• A. $1cm$
• B. $2cm$
• C. $4cm$
• D. $6cm$

Answer 1

Answer: (B)

$2cm$

$\frac{\lambda }{4}=32+0.3d$
$\frac{3\lambda }{4}=100+0.3d$
$\frac{\lambda }{2}=68cm$
$\frac{\lambda }{4}=34cmor0.3d=2cm$
