(35%) 2) (原PO註:此題是期中考題) a)Explain the physical significance of the inductance L. (6%) b)What is the geometrical meaning of the operator "curl"? Answer this question starting from the mathematical definition. (6%) c)What is Ampere's Law? (6%) d)What is the "displacement current"? (6%) e)Explain how the integration form of Ampere's Law can be obtained from the differential form. (6%) 3) a)What are the Maxwell's equation? (6%) b)Why is the EM wave in vacuum a transverse wave? (6%) c)Use Maxwell's equation to construct a physical picture and explain how an EM wave can propagate in vacuum without medium. (6%) 4) a)What are "time dilation" and "Lorentz contraction"? How are they derived? (12%) b)What are the common physical origin shared by these two phenomena? (6%) 5) a)Construct the basic assumption and rules for quantum mechanics from the experimental observations of an electron beam through double slits. (10%) b)What are the phase velocity and the group velocity of waves? (6%) c)Explain why an electron with low energy can not be confined permanently in a potential wall with finite height and width.
