Given information
The light emitted from one of these electronic transitions in the hydrogen atom caused the photoelectric effect in particular metal, while light from the other transition did not.
Step-by-step explanation
Step 1.
The photoelectric effect is only caused when there is enough threshold energy to takeout electron from the metal.
Thus, the transition that has more energy from the given transitions will cause the photoelectric effect in a particular metal.
The energy of transition is given by,
Where,
- is the energy that is required for transition.
- ….
The change in energy is calculated by
