Experimental results for the electromagnetic production of eta and K mesons are compared with QCD-inspired models. The eta mesons from the decay of S_11 resonance were used to study the momentum transfer dependence of the relevant helicity amplitude and cross section in the reaction ^1H(e,e'p)eta. The ^1H(e,e'K+)Lambda reaction was studied as a function of squared four-momentum transfer, Q^2, and of the virtual photon polarization parameter, epsilon. Both of these experiments were performed at Jefferson Lab during the early years of operation. The new precision data serve to constrain model calculations and provide new insights into the physical processes.
