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

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
