Question
When the photoelectric equation is rewritten as Vstop = (h/e)f - W/e, what does the slope of the Vstop versus frequency (f) graph represent?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 5 states, 'From Einstein's equation: hf = W + e*Vstop we can see that the straight line of the Vstop vs f graph should [after re-writing the equation as Vstop = (h/e)f - W/e] have a slope of (h/e)'.
Hint
Locate the re-written equation and the mention of the graph's slope on page 5.
