A beam of unpolarized light traveling in air (\(n_{\text{air}} = 1.0\)) strikes the flat surface of a transparent plastic block. The reflected light is observed to be completely linearly polarized when the angle of incidence is \(\theta_p = 60^\circ\). The plastic block is then replaced with a glass block that has a greater index of refraction (\(n_{\text{glass}} > n_{\text{plastic}}\)). How does the new polarizing angle \(\theta_p'\) for the glass block compare to \(60^\circ\), and why?
