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 speed of sound in air is 343m/s)

Explanation:

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

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

For fundamental frequency, n = 1

First overtone frequency,

Second overtone frequency,

Third overtone frequency

Hence, this is the required solution.

1 a

2 b

3 b

4 d

5 d

6 d

explanation:
