A physics undergrad definitely includes most of the most damning experiments in physics. Muon capture for verifying Special Relativity, the photovoltaic and single-photon double slit experiment for Quantum, the spinning mirror thing for measuring the speed of light.
You definitely see enough that you don't need to take the models on faith.
There is still a lot taken on faith for quite awhile, as the knowledge to judge the accuracy/meaning of each of those is also built on a lot of theories and prior experiments which are not usually personally tested. But Physics as noted is much less so than most everything else.
