What transition would emit the longest wavelength of light?
What transition would emit the longest wavelength of light?
Wavelength is inversely proportional to energy. Since the transition from n=4 to n=3 is the lowest energy transition, it would have the longest wavelength.

A 3.0 eV light is shined on Gold ( Փ = 5.1 eV), silver (Փ =4.26 eV), Cesium (Փ = 2.1 eV), and Platinum (Փ = 6.35). If Փ is the work function of the metal, what metal would have electrons ejected?

The work function is the energy required to remove an electron from a metal. Only Cs metal has a work function less than the energy of the light.
