WebThe wavemeter is generally used for the measurement of the wavelength of light. Light rays which are delivered in the form of laser beams are measured by a wavemeter. A wavemeter also acts as an important device in measuring the wavelength or the frequency of an electromagnetic signal or radio signal. An absorption wavemeter is a simple electronic instrument used to measure the frequency of radio waves. It is an older method of measuring frequency, widely used from the birth of radio in the early 20th century until the 1970s, when the development of inexpensive frequency counters, which have far greater accuracy, made it largely obsolete. A wavemeter consists of an adjustable resonant circuit calibrated in frequency, with a meter or other means to measure the voltage or c…
