Use the graph below to answer the following question:
Graph titled maximum kinetic energy of ejected photo electron versus incoming frequency is shown. The y axis is labeled maximum kinetic energy and scales from negative 3 to positive 3 electron volts. The x axis is labeled frequency from 0 to 11 times 10 to the 14 hertz. A line connects the points 0, negative 2 and 2.5, negative 1 and 5, 0 and 8, 1 and 10, 2.
What is the threshold frequency of the experimental photo-missive material?
10.0 × 1014 Hz
5.0 × 1014 Hz
2.6 × 1014 Hz
0.5 × 1014 Hz
