Which of the following graphs correctly represents the variation of maximum kinetic energy () of emitted photoelectrons with the frequency () of incident radiation?
- A.A straight line parallel to the frequency axis.
- B.A parabola opening upwards.
- C.A straight line with a positive slope that intersects the frequency axis at the threshold frequency.Correct answer
- D.A straight line passing through the origin.
Solution
According to Einstein's equation, . This is a linear equation of the form , where the slope is and the intercept on the -axis is (threshold frequency).
