Properties of the electromagnetic tensor: explicitly show that fve is a lorentz invariant b. explicitly show that ghgv 2. 2(e2/c2 - b2), which, as you showed in problem 1(a) a. uv -flvfuv which is also a lorentz invariant 'μν explicitly show that fgv = -2(e -b), which, as you showed in problem 1(a), is lorentz invariant d. for what important physical phenomenon explain μν. μν c. are the invariants in (a) and (b) equal to zero?
