In a resonance tube experiment, a tuning fork resonates with air column of length $12 \mathrm{~cm}$ and again resonates when air column is $38 \mathrm{~cm}$ long. The end correction will (b)
  1. $0.25 \mathrm{~cm}$
  2. $0.5 \mathrm{~cm}$
  3. $1 \mathrm{~cm}$
  4. $0.75 \mathrm{~cm}$

Solution

$e=\frac{l_{2}-3 l_{1}}{2} \quad\therefore e=\frac{38-36}{2}=1 \mathrm{~cm}$
