Question

Relation between kinetic energy and frequency

Answer 1

Answer:

The general formula for Kinetic Energy is, K=1/2 m*v^2 It can also be written as 1/2 p^2/m relationship between momentum and wavelength for matter waves is given by p = h/λ, and the relationship energy and frequency is E = hf.

Hope it will be helpful :)

Answer 2

Answer:

The two factors affecting maximum kinetic energy of photoelectrons are the frequency of the incident radiation and the material on the surface. As shown in the graph below, electron energy increases with frequency in a simple linear manner above the threshold.
