For the arrangement of Figs. 38-14 and 38-15, electrons in the incident beam in region 1 have a speed of 1.60 107 m/s and region 2 has an electric potential of V2 ! #500 V.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 3.00 " 109 electrons against the potential step, approximately how many will be reflected?
