According to Einstein’s photoelectric equation, the graph between the kinetic energy of photoelectrons ejected and the frequency of incident radiation is:

1. Kinetic Energy vs Frequency (linear graph)
2. Kinetic Energy vs Frequency (non-linear graph)
3. Kinetic Energy vs Frequency (constant graph)
4. Kinetic Energy vs Frequency (exponential graph)

Correct answer: Kinetic Energy vs Frequency (linear graph)

Solution

According to Einstein's photoelectric equation, the kinetic energy of photoelectrons is directly proportional to the frequency of incident radiation above the threshold frequency. This results in a linear graph with a slope equal to Planck's constant.
