Describe an experiment to determine end- correction of resonance tube.

Describe an experiment to determine end- correction of resonance tube.

Solution

• A sounding tuning fork of known frequency s is held over open end of a tube filled with water
• The water is gradually lowered until a loud sound is heard.
• The length L of air column is measured,
• The procedure is repeated using tuning forks of different frequencies and corresponding length L measured and recorded.
• The results of L, f and 1/f are tabulated
• A graph of L against1/f give an intercept c, the end correction of resonance tube.
