The wavelength in air of the sound from a violin is 4.00x10⁻¹m. What is the frequency of vibration of the violin? (Ans: 850Hz)

Answer 1

given that speed of air is 3.40x10²m/s

Answer 2

frequency = speed / wavelength

speed of sound in air is ... 343 m/s
... it is dependent on barometric pressure, temperature, humidity, etc.

thanks for the correction

Answer 3

V/F = 0.4 m.
340/F = 0.4,
F = ?
