Calculating Kinetic Energy with E=h*f

AI Thread Summary
The equation E=h*f calculates the energy of each photon, but to find kinetic energy, the equation K=1/2*m*v^2 is typically used. The discussion explores the relationship between kinetic energy and the wave properties of photons, suggesting that velocity can be expressed as v=A*cos(t/T - x/λ). Clarification is sought on how to connect these concepts effectively. Understanding the transition from photon energy to kinetic energy is crucial for applying these equations correctly. The conversation emphasizes the need for a clear framework when integrating these physical principles.

There is this equation: E=h*f that give us the energy of each photon.
If we want to find kinetic or dynamic energy,what equation we will use?
Something like K=1/2*m*v^2 (where v is the speed and we have v=A*cos(t/T- x/λ)) ?
