Abstract: We present measurements of three distinctive state-dependent wavelengths for the $^{1}S_{0}\text{\ensuremath{-}}^{3}P_{0}$ clock transition in ${}^{\text{174}}\text{Yb}$ atoms. Specifically, we determine two magic wavelengths at 652.281(21) and $542.502\phantom{\rule{0.16em}{0ex}}05(19)\phantom{\rule{0.16em}{0ex}}\text{THz}$, where the differential light shift on the $^{1}S_{0}\text{\ensuremath{-}}^{3}P_{0}$ clock transition vanishes, and one tune-out wavelength at $541.8325(5)\phantom{\rule{0.16em}{0ex}}\text{THz}$, where the polarizability of the $^{1}S_{0}$ ground state exhibits a zero crossing. The two magic wavelengths are identified by spectroscopically interrogating cold ${}^{\text{174}}\text{Yb}$ atoms on the clock transition in a one-dimensional optical lattice. The ground-state tune-out wavelength is determined via a parametric heating scheme. With a simple empirical model, we then extrapolate the ground- and excited-state polarizability over a broad range of wavelengths in the visible spectrum.
