What is the reflection coefficient

Reference no: EM13985790

For the arrangement of Figure (a) and Figure (b), electrons in the incident beam in region 1 have energy E = 804 eV and the potential step has a height of U₁ = 603 eV. What is the angular wave number in (a) region 1 and (b) region 2? (c) What is the reflection coefficient? (d) If the incident beam sends 6.10 x 10⁵ electrons against the potential step, approximately how many will be reflected?
