What will be the fundamental frequency and first three overtones for a 26cm long organ at 20°C if it is open ( at 20°C, the spee
kakasveta [241]

Explanation:

The frequency of an organ pipe if it is open is given by :

f=\dfrac{nv}{2l}

v is speed of sound in air is 343 m/s at 20°C

For fundamental frequency, n = 1

f=\dfrac{1\times 343}{2\times 0.26}\\\\f=659.61\ Hz

First overtone frequency,

f_1=2f\\\\f_1=2\times 659.61\\\\f_1=1319.22\ Hz

Second overtone frequency,

f_2=3f\\\\f_2=3\times 659.61\\\\f_2=1978.83\ Hz

Third overtone frequency

f_3=4f\\\\f_3=4\times 659.61\\\\f_3=2638.44\ Hz

Hence, this is the required solution.

But one thing, NEXT TIME TELL US THE QUESTION FIRST AND DON'T JUST LEAVE BLINDLY ASKING SOMETHING.
