don;t worry about the figure ? its in the book i cannot tell you the right here but has nothing to do with the answer .. acutally .203 i just plugin the values but i am sure i am not right so please help me out i already set up the equation but still getingg problem to solve this problem !or to...

Quntum physics ! barrier energy ! Consider a potential energy barrier like that of Fig. 38-15 but whose height U0 is 5.4 eV and whose thickness L is 0.73 nm. What is the energy of an incident electron whose transmission coefficient is 0.0017? I tried to solve the problem my self but could...

1. Compton scattering from electrons is most easily observed for: *microwaves *infrared light *visible light *ultraviolet light *x rays I Think it refer to x ray . but not sure what do you think guyz .. please tell me if you can 2.Which of the following electromagnetic radiations has...

megnetic force problem help please A charged particle (q = +2.7 µC) moves at speed v0 = 50 m/s in the +x-direction. At x = 0 it enters a region where a constant magnetic field B = 3.4 T is directed in the +z direction ? What are the component of electric field ? i got the Ex and Ez which are...
