    Why does an electron have minimum kinetic energy when its momentum is 2h/λ?

    Ahhh alright. Just want to make sure that my solution is reasonable before I go to discuss with my lecturer about the wrong solution. Thanks for helping 😇

    Why does an electron have minimum kinetic energy when its momentum is 2h/λ?

    my solution is 180 degree (pi radian) but the solution provided is 0 degree. That’s why I was asking why shouldnt it be 180 degree :)

    Why does an electron have minimum kinetic energy when its momentum is 2h/λ?

    The solution is posted by my lecturer so I’m sure that it’s the solution for this question. My attempted solution assumed that the final photon momentum would be -h/ λ ( the photon scattering angle is 180). Is there anything wrong with my attempted solution?

    Why does an electron have minimum kinetic energy when its momentum is 2h/λ?

    Solution given: The minimum kinetic energy electrons will arise from a change in photon energy on scattering that is a minimum and this will arise from the smallest wavelength change of the photon. The Compton scattering formula is ∆λ = (h/mc)(1 − cos φ) which is minimised when 1 = cos φ. This...

    Two traveling waves g(x,t) = Asin(kx-wt) and h(x,t) = Asin(kx+wt+phi)

    Hi haruspex, thank you for yr time to have a look at my question. the Figure doesn’t include nodes/anti nodes.
