Waves question

2020 · 8 Jan · Shift 1 · Q49

JEE MainPhysicsWavesNumerical+4 / −1
A one metre long (both ends open) organ pipe is kept in a gas that has double the density of air at STP. Assuming the speed of sound in air at STP is 300 m/s, the frequency difference between the fundamental and second harmonic of this pipe is ‾\underline{\hspace{2cm}}​ Hz.
