Understand the Problem

The question seems to discuss the total energy of a free particle in the context of quantum mechanics, specifically referencing the de Broglie wavelength and the equation relating energy and momentum.

Answer

E = p²/2m transforms to ħω = ħ²k²/2m using de Broglie relations.

The conversion of E = p²/2m to ħω = ħ²k²/2m using de Broglie relations shows the wave-particle duality, linking particle momentum with wave characteristics.

Answer for screen readers
