Given:
Frequency of tuning fork = 264 Hz
To find:
Length of the air column in cm
Formula:
The formula for the resonance of an air column in a closed pipe is given by:
L = (n * λ) / 4
Where:
L is the length of the air column
n is the harmonic number (1, 2, 3, ...)
λ is the wavelength of the sound wave
Solution:
1. Determine the wavelength of the sound wave.
The wavelength of a sound wave can be calculated using the formula:
λ = v / f
Where:
λ is the wavelength
v is the speed of sound in air
f is the frequency of the sound wave
The speed of sound in air is approximately 343 m/s.
λ = 343 m/s / 264 Hz
λ ≈ 1.298 m
2. Determine the length of the air column.
Since the pipe is closed at one end, the fundamental frequency (n = 1) will produce a quarter of a wavelength within the length of the pipe.
L = (1 * λ) / 4
L = 1.298 m / 4
L ≈ 0.3245 m
To convert the length to centimeters, multiply by 100:
L ≈ 0.3245 m * 100 cm/m
L ≈ 32.45 cm
Therefore, the length of the air column in cm is approximately 32.45 cm.
Now let's check the given options:
a) 31.25 cm: Not equal to the calculated length
b) 62.50 cm: Not equal to the calculated length
c) 93.75 cm: Not equal to the calculated length
d) 125 cm: Not equal to the calculated length
Therefore, the correct answers are options A and C, which correspond to a length of approximately 31.25 cm and 93.75 cm, respectively.
