Answers about variable relation of pre-service teachers (PSTs) on item 2.

Connection of variables Number of PSTs
As the work function increases, the threshold frequency also increases. 7
As the Work function increases, the threshold frequency increases, leading to a light frequency rise. 3
As the Work function increases, the threshold frequency increases, which decreases the maximum kinetic energy of photoelectrons. 1
As the Work function increases, the bonding energy increases, and the bonding energy increase contributes to the threshold frequency rise. Ultimately, this leads to an increase in light frequency. 2
As the work function increases, the light frequency also increases. 4
As the work function increases, the binding energy increases, which increases the light frequency. 1
As the work function increases, there is no change in the light intensity. 1
As the work function increases, the photocurrent also increases. 1
As the work function increases, the photocurrent decreases. 1
