A photon has the same momentum as an electron moving with a speed of 1.92×105 m/s. What is the wavelength of the photon?
here ,
speed of photon , v = 1.92 *10^5 m/s
momentum of electron , p = m * v
wavelength of photon = h/mv
wavelength of photon = 6.626 *10^-34/(9.11 *10^-31 * 1.92 *10^5)
wavelength of photon = 3.79 *10^-9 m
the wavelength of the photon is 3.79 *10-9 m

3. What speed must an electron have if its momentum is to be the same as that of an X-ray photon with a wavelength of 0.80 nm?
A photon moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0410 nm. After the collision, the electron moves at an angle α below the +x-axis, while the photon moves at an angle θ = 73.3° above the +x-axis. (For the purpose of this exercise, assume that the electron is traveling slow enough that the non-relativistic relationship between momentum and velocity can be used.) (a) What is the angle α (in degrees)?...
