A closed organ pipe has length ‘ λ ‘. The air in it is vibrating in 3 rd overtone with maximum amplitude 'a '. Find the amplitude at a distance of λ /7 from closed end of the pipe
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Equation of stationary wave from closed end = a sink x cos ωt
Now at x = 
= λ
Amplitude = a sin kx = a sin 
= a sin 
= a sin 
= a
