Intensity and frequency formula

WebA commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor. WebFormula 1: The frequency formula in terms of time is given as: f = 1/T where, f is the frequency in hertz measured in m/s, and T is the time to complete one cycle in seconds Formula 2: The frequency formula in terms of wavelength and wave speed is given as, f = 𝜈/λ where, 𝜈 is the wave speed in m/s, and λ is the wavelength of the wave in m
