An electron strikes the back of a TV screen at 1/10 the speed of light.
What is the speed of the electron?
What is the momentum of the electron?
What is the deBrogile wavelength of the electron?

  • Physics - ,

    v = 0.1 c = ?
    momentum = m*v = ?
    de Broglie wavelength = h/{momentum) = ?

    You do the numbers. You will need to look up the speed of light (c), electrom mass (m), and Planck's constant (h).

    I am using nonrelativistic (before Einstein) formulas. The correct formulas will differ by a factor of sqrt [1 - (v/c)^2]= 0.995

  • Physics - ,

    Consider the de Broglie wavelength of an electron that strikes the back face of one of the early models of a TV screen at 1/10 the speed of light
