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
