find the wavelength of a sound wave with a frequency of 4.010^4.
user
the wavelength of a sound wave with a frequency of 4.0×10^4 is 7.5 meters. this is calculated by using the formula wavelength (λ) = speed of sound (v) divided by frequency (f): λ = v/f. the speed of sound in air is 343 m/s, so the wavelength is 343 m/s divided by 4.0×10^4 hz, which is equal to 7.5 m.
