Question 10
Observation
(a) (i) End correction of a resonance tube
The distance between the open end of the resonance tube and the antinode position/vibrating tuning fork.
(ii) Dimension of end correction
[End correction] = L
(ii) Precautions in a resonance tube experiment
- Reading of length taken at eye level.
- Tuning fork struck gently.
- Vibrating prongs of the tuning fork not touching the tube.
- Avoiding parallax when reading the meter rule.
- Resonance tube kept vertical.
(ii) Calculation of distance
In 4 complete cycles
distance = 4(3)
= 12 cm
