( ii ) Kinetic energy of recoil electron
E k = hc / λ – hc / λ ’ ( iii ) Direction of recoil electron tan θ = λ sin φ / λ ’ – λ cos φ ( iv ) Compton wavelength of electron = h / m o c = 0.024 A ( v ) Maximum Compton shift ( Δλ ) max = 2h / m o c 0.0048 A
Matter Waves on de-Broglie Waves
A wave is associated with every moving particle , called matter or de-Broglie wave . de-Broglie Wavelength
If a particle of mass m is moving with velocity v , then wavelength of de-Broglie wave associated with it is given by
λ = h / p = h / mv de-Broglie wavelength of an electron is given by λ = h / mv = h / √2me V = 12.27 / √V A .
