Light of a given wavelength is used to illuminate the surface of a metal, however, no photoelectrons are emitted. In order to cause electrons to be ejected from the surface of this metal you should: a. use light of the same frequency but decrease its intensity b. use light of a higher frequency c. use light of the same frequency but increase its intensity d. use light of a longer wavelength

Consider the various frequencies of the three photons emitted from the following three individual electron transitions in the figure below: n=3 to n=2; n=2 to n=1; n=3 to n=1. What energy level does an electron land on when light is emitted that is part of the ultraviolet region?

a. n=2

b. n=3

c. n=1
