So lets assume, that Wave 1 has a wavelength of 1 cm and Wave 2 has a wavelength of 2 cm. So the speed at which a wave is moving is a very important factor when determining its frequency.Īn important point to note is that two waves with different wavelengths can have the same frequency. If a wave is moving faster, the number of complete wave cycles that will complete in 1 second is higher than when compared to a slower wave. In the case of traveling waves, the frequency of a wave is correlated to the wavelength of the wave and the speed at which the wave is traveling. Relationship between frequency and wavelength The Wavelength is inversely proportional to frequency. The wavelength applies to both traveling waves and standing waves. It is represented by lambda (λ) and has units of distance like meters, cm, mm etc. The wavelength of a wave is the distance between two adjacent peaks or troughs of adjacent cycles. So if a wave repeats 5 times in one second its frequency would be 5 Hz. The unit of frequency is Hz which corresponds to the number of waveforms that repeat in 1 second. The frequency of a waveform is the number of times a complete waveform is repeated in a fixed time period.
