Speed of sound in air

Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f. … The Speed of Sound. a. one-ninthb. one-thirdc. the same asd. three times larger thanThe Speed of Sound – The Physics Classroom www.physicsclassroom.com › class › sound › Lesson-2 › The-Speed-of-So…

The frequency of a sound wave not only refers to the number of back-and-forth vibrations of the particles per unit of time , but also refers to the number of compressions or rarefactions that pass a given point per unit of time.

To calculate the frequency of a wave, divide the velocity of the wave by the wavelength . Write your answer in Hertz, or Hz, which is the unit for frequency.
