When you increase only the intensity of the light onto the emitter, you measure
  A. A decrease in the necessary stopping voltage
  B. An increase in the necessary stopping voltage
  C. No change in either current or stopping voltage
  D. Either a or c. You cannot determine which from the information given.
  E. An increased current

Question 2

How did Planck modify the classical theory of blackbody radiation to correctly determine his radiation law?
 

A.He found that the blackbody model was incorrect for purposes of theory
  B.He accepted the Stefan-Boltzmann law
  C. He assumed light was absorbed and emitted in quanta
  D.He realized that the charge of the electron was not quantized
  E.He proved the necessity of relativistic considerations

Answer to Question 1

E.
From the increase in intensity of light, more photons hit the emitter, therefore more electrons are freed and given enough kinetic energy to jump the gap. You know that the current will increaseas opposed to staying at zerobecause the most energetic electrons already have established the current I.

Answer to Question 2

Assuming that light was absorbed and emitted in discrete quantities known as quanta was the only way for Planck's radiation law to work empirically. He also found that the producers of the photons must have discrete energies based on Planck's constant.
C.
