Question

The fundamental frequency of the air column in a closed pipe is 512 Hz. If the pipe is open from both the ends, the fundamental frequency will be ........ Hz.
(a) 1024
(b) 512
(c) 256
(d) 128

Answer 1

Answer:

256is fundamental frequency

Answer 2

Answer:

(a) 1024  

Explanation:

As per the question,

We have been provided that

The fundamental frequency of the air column in a closed pipe is =  512 Hz.

As we know,

The fundamental frequency of open pipe is equal to the two times of the fundamental frequency of the air column in a closed pipe.

Therefore,

Fundamental frequency of open pipe = 2 × Fundamental frequency of close pipe

⇒ Fundamental frequency of open pipe = 2 × 512

⇒ Fundamental frequency of open pipe = 1024 Hz

Hence, the correct option is (a).
