A light source emitting radiation at 7.00∙1014 Hz is just capable of ejecting photoelectrons from Eiteneerium (Ei).
A. What can be done with the light to produce no photoelectrons? Explain conceptually in one sentence.
B. What is the effect of increasing intensity of this light?
C. What is the work function of Eiteneerium?
D. If the frequency of light is now doubled, what is the speed of the emitted electrons?
