PHY 104 Photo Electric Emission Objective Question

Question

What does the slope of the V-stop vs. frequency graph represent according to Einstein's photoelectric equation?
Options
A The work function (W).
B Planck's constant (h).
C The charge of an electron (e).
D The ratio of Planck's constant to the charge of an electron (h/e).
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Page 5 states: '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

Examine the equation rearrangement for V-stop on page 5 and identify the term multiplying the frequency 'f'.
