Answers about variable relation of pre-service teachers (PSTs) on item 10.

Connection of variables Number of PSTs
As the light intensity increases, the number of photoelectrons also increases. 10
As the light intensity increases, the number of photons increases, which leads to a rise in the number of photoelectrons. 2
As the light intensity increases, the number of photons increases, which leads to an increase in the intensity of photocurrent. 2
As the number of photons increases, the number of photoelectrons also increases. 1
Since the light energy does not change, the number of photoelectrons does not change. 1
Since the voltage intensity does not change, the number of photoelectrons does not change. 3
Since light intensity does not change, the number of photoelectrons does not change. 2
