An air column, closed at one end and open at the other, resonates with a tuning fork when the smallest length of the column is 50  cm . The next larger length of the column resonating with the same tuning fork is:
  1. 66.7  cm
  2. 100  cm
  3. 150  cm
  4. 200  cm

Solution

First minimum resonating length for closed organ pipe =λ4=50 cm
∴ Next larger length of air column =3λ4=150 cm
