A wave-meter for wave-lengths of about a centimetre, with an accuracy of 1 to 2 parts in 10 000, is described, based on a new system of coupling to the H0 mode in resonant cavities which avoids the excitation of other modes. An indirect effect due to simultaneous resonance in two different modes is discussed in relation to the measurement of absorption by resonant cavities.
