- From the graph, find the value, including its SI unit, of the following:
i. the threshold frequency;
ii. the work function of the surface;
iii. Planck's constant
- Relevant Equations
- N/A
i. the threshold frequency;
3.9x10^14hz? it appears the line intersects at 3.9ii. the work function of the surface;
6.626x10^-34x3.9x10^14= 2.58414 × 10^-19J
iii. Planck's constant
