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.

Read moreWhat is frequency of sound in physics?
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.
Read moreHow do you find the frequency of sound?
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.
Read moreHow do you find the frequency?
To calculate frequency, divide the number of times the event occurs by the length of time . Example: Anna divides the number of website clicks (236) by the length of time (one hour, or 60 minutes). She finds that she receives 3.9 clicks per minute.
Read moreWhat is the formula for frequency of a wave?
Frequency is the number of completed wave cycles per second. This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds.
