Fundamental frequency of closed pipe is 75 .the frequency of the first overtone is? ?

The fundamental frequency of a closed pipe is given by the formula:

f = v / (2L)

where:
f = fundamental frequency
v = speed of sound in air (approximately 343 m/s)
L = length of the closed pipe

Given that the fundamental frequency is 75 Hz, we can rearrange the formula to solve for the length of the closed pipe:

75 = 343 / (2L)
2L = 343 / 75
L = 343 / (2 * 75)
L = 2.29 meters

For a closed pipe, the first overtone is three times the fundamental frequency. Therefore, the frequency of the first overtone is:

3 * 75 = 225 Hz

So, the frequency of the first overtone of the closed pipe is 225 Hz.
