What is the fundamental mode?
(N/A) The fundamental mode,also known as the first harmonic,is the lowest frequency of vibration of a system (such as a string or an air column). In this mode,the system vibrates with the simplest possible standing wave pattern,having the minimum number of nodes and antinodes. For a string fixed at both ends,the fundamental mode corresponds to a length $L = \lambda / 2$,where $\lambda$ is the wavelength. The frequency of this mode is given by $f = v / (2L)$,where $v$ is the wave speed.
