हिन्दीThe fundamental frequency of an open organ pipe of length \( L \) is \( \nu_0 \). What is the frequency of its third harmonic?
View Answer & Solution
Correct answer · Option B
\( 3\nu_0 \)
Explanation
For an open pipe, all harmonics are present, so the frequency of the \( n \)-th harmonic is \( \nu_n = n\nu_0 \). For \( n=3 \), it is \( 3\nu_0 \).
