Find the length of an organ pipe closed at one end that produces a fundamental frequency of 256 hz when air temperature is 18° c a. 0.167 m b.0.334 m c. 0.667 m o d. 1.336 m

B. 0.334 m

Explanation:

Given that fundamental frequency of organ pipe which is closed at one end is,

And the temperature of air is,

Now convert temperature in kelvin,

Now the fundamental frequency formula  when the organ pipe is open at one end.

Here, v is the velocity of sound, L is the length of organ pipe.

For further solving it for L.

And also we know that,

Here, is rthe speed of sound at room temperature and the value of this is,

.

Now,

Now put this value in L equation,

Therefore, the length of an organ pipe is 0.334 m

answer: (431,2)
