An important new probe of the physics of large-scale radio jets is possible with the discovery of resolved X-ray/optical jets. The optical emission comes from high energy electrons, which have short radiative lifetimes and so pinpoint particle acceleration sites. Spectral energy distributions of knots in two jets suggest the X-rays come from lower energy electrons inverse-Compton scattering the {beamed} cosmic microwave background. This requires the jet to be still relativistic on kiloparsec scales {out to 1 Mpc for the high-redshift jets.}. This model robustly constrains both the bulk relativistic speed and the minimum electron energy in the jet, which together determine the total jet power. To probe jet energetics and physics generally, and to test the ``Compton/CMB'' interpretation specifically, we propose deep HST imaging of three X-ray/optical jets {PKS 1127-145, PKS 0637-752, 3C 371} and one optical jet {PKS 2201+044}, plus Chandra observations of the latter two. The multiwavelength spectra of individual knots differ significantly, as does one jet from another, indicating the need for detailed high- resolution study of more than 1 or 2 jets. Along with the well-observed 3C 273 and M 87 jets, the 4 proposed targets are the only known {or likely} nonthermal X-ray jets readily detected with Chandra and HST.
