  We report an analysis of new $V$ and $I$ CCD time-series photometry of the
globular cluster NGC 6934. Through the Fourier decomposition of the RR Lyrae
light curves, the mean values of [Fe/H] and the distance of the cluster were
estimated, we found; [Fe/H]$_{UVES}$=-1.48$\pm$0.14 and $d$=16.03$\pm$0.42 kpc,
and [Fe/H]$_{UVES}$=-1.43$\pm$0.11 and $d$=15.91$\pm$0.39 kpc, from the
calibrations of RRab and RRc stars respectively. Independent distance
estimations from SX Phe and SR stars are also discussed. Individual absolute
magnitudes, radii and masses are also reported for RR Lyrae stars. We found 12
new variables: 4 RRab, 3 SX Phe, 2 W Virginis (CW)and 3 semi-regular (SR). The
inter-mode or "either-or" region in the instability strip is shared by the RRab
and RRc stars. This characteristic, observed only in some OoI clusters and
never seen in an OoII, is discussed in terms of mass distribution in the ZAHB.
