what units are wavelengths measured in
We already know that when we talk about wavelength, we are talking about the distance between two peaks of a wave. Wavelength is usually measured in meters (m). Frequency is the number of cycles of a wave to pass some point in a second. The units of frequency are thus cycles per second, or Hertz (Hz).e already know that when we talk about wavelength, we are talking about the distance between two peaks of a wave.
