Answer #1

By compton equation we know that scattering of wavelength is

Δ=(h/mc)(1–cos) ,where

  • h = 6.62607 × 10-34 J/s is the Planck constant,
  • m [kg] is the mass of an object,=9.11×10-31
  • c = 3×108 m/s is the speed of light,
  • =29.6°

Now

Δ=[(6.62607×10-34/(9.11×10-31×3×108)]×(1-cos29.6°)

Δ=3.16×10-13m=0.000316nm
