Three successive resonance frequencies in an organ pipe are 1310,1834 and

2358 \mathrm{Hz}

. The frequency of

1^{\text {st }}

overtone (in

\mathrm{Hz}

) is (velocity of sound in air is

340 \mathrm{m} / \mathrm{s}

)

View answer and explanation

Correct option: B

786

Option B (786) is correct because the difference between successive resonance frequencies is constant in an organ pipe, allowing us to determine the fundamental frequency and then the first overtone.
