Question

Using the velocity of sound at 343 m/s and given the frequencies of a piano scale, compute the wavelengths of a note that has a frequency of 440 Hz. a) Wavelength = 0.778 meters b) Wavelength = 1.546 meters c) Wavelength = 2.123 meters d) Wavelength = 0.245 meters

Answer 1

the right answer is a ) wavelength =0.778 m

Step-by-step explanation:

To compute the wavelength of a note with a frequency of 440 Hz using the velocity of sound at 343 m/s, you can use the formula:

Wavelength (λ) = Velocity of Sound (v) / Frequency (f)

Wavelength (λ) = 343 m/s / 440 Hz

Wavelength (λ) ≈ 0.779 meters

So, the correct answer is:

a) Wavelength = 0.778 meters
