The graph of kinetic energy against the frequency \((\mathrm{V})\) of incident light is as shown in the figure. The slope of the graph and intercept on \(X\) axis respectively are
- A Planck's constant, threshold frequency
- B work function, maximum K.E
- C maximum K.E, threshold frequency
- D Planck's constant, work function
Answer & Solution
Correct Answer
(A) Planck's constant, threshold frequency
Step-by-step Solution
Detailed explanation
(A)
\(\mathrm{KE}=\mathrm{h} v-\phi_{0}\)
\(y=m x-c\)
\(\therefore \mathrm{m}=\mathrm{h}, \mathrm{c}=\phi_{0}\)
\(\mathrm{KE}=\mathrm{h} v-\phi_{0}\)
\(y=m x-c\)
\(\therefore \mathrm{m}=\mathrm{h}, \mathrm{c}=\phi_{0}\)
