Detailed explanation-1: -The frequency formula in terms of wavelength and wave speed is given as, f = / where, is the wave speed, and is the wavelength of the wave. The frequency formula in terms of angular frequency is given as, f = /2 where is the angular frequency.
Detailed explanation-2: -If the wavelength and speed of a wave are known, these can be used to find the frequency of a wave using the equation f=v f = v , where is the wavelength in meters and v is the speed of the wave in m/s. This also gives the frequency of the wave in Hertz.
Detailed explanation-3: -Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.
Detailed explanation-4: -Wave speed equation (Speed = Wavelength x Frequency) relates wave speed to wavelength and frequency. When the wavelength and frequency are known, this equation can be used to calculate wave speed.
