We present measurements of three distinctive state-(in)dependent wavelengths for the 1S0−3P0 clock transition in 174Yb atoms. Specifically, we determine two magic wavelengths at 652.281(21)THz and 542.50205(19)THz, where the differential light shift on the 1S0−3P0 clock transition vanishes, and one tune-out wavelength at 541.8325(5)THz, where the polarizability of the 1S0 ground state exhibits a zero crossing. The two new magic wavelengths are identified by spectroscopically interrogating cold 174Yb 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.
