ممكن مساعده في حل هذي الاسئلة
A particle is confined to a one-dimensional box on the x-axis between x = 0 and x = L. The
potential height of the walls of box is infinite. The normalized wave function of the particle
which is in the ground state is given by:

a) 0.20 b) 0.22 c) 0.24 d) 0.26 e) 0.28
A low density beam of 8.0 eV electrons is incident at a potential barrier 14 eV in height and
0.8 nm in width. The fraction of the beam that is transmitted through the barrier is:
a) 1.2x10-7 b) 2.5x10--6 c) 2.8x10-6 d) 8.2x10-9 e) 1.6x10
حاولت ان اعرف طريقة الحل لكن للاسف لم اتوصل لها
وجزاكم الله خير
