One student generates a short, loud sound of wavelength 0.7576 m. Another student, who is 100 m away, hears the sound exactly 0.300 s later. What is the frequency of this sound?
Please help
speed = 100/.3 = 333 m/s
.7576 = 333* T
T = .00227 seconds
f= 1/T = 440 Hz
To find the frequency of the sound wave, we can use the formula:
Frequency (f) = Speed of sound (v) / Wavelength (λ)
First, let's find the speed of sound. The speed of sound in air is approximately 343 m/s.
Next, let's convert the time delay from seconds to milliseconds since the wavelength is given in meters.
0.300 s = 300 milliseconds
Now, we can calculate the frequency using the formula:
Frequency (f) = 343 m/s / 0.7576 m
Frequency (f) = 452.51 Hz
Therefore, the frequency of the sound wave is approximately 452.51 Hz.
