**1. The problem statement, all variables and given/known data**

Plotting stopping voltage vs. frequency, we expect to find:

a) the slope is related to Planck’s constant and the intercept is related to the work function of the metal

b) the slope is related to the work function of the metal and the intercept is related to Planck’s constant

c) the slope is the work function of the metal divided by Planck’s constant and the intercept is irrelevant

d) the intercept is Planck’s constant divided by the work function of the metal and the slope is irrelevant

**2. Relevant equations**

Vs= (h/e)f – (work function/e)

**3. The attempt at a solution**

I think the answer is (A) because the planck’s constant is the slope and the intercept is the work function, but I am not sure. Any help would be great 🙂
