Q8.31Multiple choice
A plane EM wave travelling in vacuum along z direction is given by E = E 0 sin(kz – ωt )ˆi and B = B0 sin(kz – ωt )ˆj .
This question refers to a figure in the original PDF.
- (i)Evaluate E.dl over the rectangular loop 1234 shown in Fig 8.2.
- (ii)Evaluate B.ds over the surface bounded by loop 1234. Electromagnetic Waves –dφB E0 x
- (iii)Use equation E.dl =to prove B = c . dt 0
- (iv)By using similar process and the equation 4 3 dφ E 1 B.dl = µ0 I + ε 0 dt , prove that c = µ0ε 0 h
