6. Monochromatic light falling on the surface of an active metal causes electrons to be ejected from the metallic surface with a maximum kinetic energy of E . What would happen to the maximum energy of the ejected electrons if the frequency of the light were doubled?
A) the maximum energy of the electrons would be 1/2E
B) the maximum energy of the electrons would be (2)E
C) the maximum energy of the electrons would be 2E
D) the maximum energy of the electrons would be greater than 2E
