The vibration frequency of the tuning fork is 440 Hz. What is the sound wavelength from a tuning fork in air if the speed of sound propagation at 0 ° C in air is 330 m / s?
v = 440 Hz.
V = 330 m / s.
λ -?
A tuning fork vibrating with a frequency v excites a sound wave of the same frequency v in the air around it.
The frequency of the wave v and the wavelength λ are related to each other by the formula: V = v * λ, where V is the speed of propagation of the sound wave.
λ = V / v.
λ = 330 m / s / 440 Hz = 0.75 m.
Answer: the length of the sound wave in air is λ = 0.75 m.
