what is the formula for frequency in a wave. Another unit for frequency is the Hertz abbreviated Hz where 1 Hz is equivalent to 1 cyclesecond. Frequency Formula Frequency is the number of cycles in a unit of time.
Therefore the frequency of the light wave is 42 1014 Hz. Frequency is equal to 1 divided by the period which is the time required for one cycle. Thus the wavelength to frequency formula is.
T period 1 f frequency.
Wave frequency in Hertz. Therefore the frequency of the light wave is 42 1014 Hz. For periodic waves in nondispersive media that is media in which the wave speed is independent of frequency frequency has an inverse relationship to the wavelength l lambda. Given this definition it is reasonable that the quantity frequency would have units of cyclessecond wavessecond vibrationssecond or somethingsecond.
