Answer
1) Electron
2) Light
Work Step by Step
1) Currently accepted models of the atom is not depicted correctly as (Bohr) models represented hydrogen and hydrogen-like atomic molecules.
Lastly, electron orbit changes were very arbitrary for the Bohr model as the actual small energy shifts in the orbits could not be explained in the model.
2) Currently accepted models of lights often assume that the light that is travelling is in a (assumed) "natural" environment, or an environment where light is not altered through means such as factors that may change the light. Such models, therefore, are inaccurate due to inability to consider factors that may render such models indefinite.
