Calculate the average kinetic energy

WebIf you multiply the kinetic energy term by $\lambda$ and the potential energy term by $\mu$, you have essentially the same Hamiltonian, so you can write down the ground state energy without much effort. The derivatives w.r.t. $\lambda$ and $\mu$ will then give you the two desired expectation values. WebSep 12, 2024 · The potential energy associated with a wavelength of the wave is equal to the kinetic energy associated with a wavelength. The total energy associated with a wavelength is the sum of the potential energy and the kinetic energy: Eλ = Uλ + Kλ = 1 4μA2ω2λ + 1 4μA2ω2λ = 1 2μA2ω2λ.
