Q8.2Multiple choice
A linearly polarized electromagnetic wave given as E = E ˆi cos (kz – ω t ) is incident normally on a perfectly reflecting infinite wall at z = a. Assuming that the material of the wall is optically inactive, the reflected wave will be given as
- (a)Er = – Eo ˆi cos (kz – ω t ) .
- (b)E r = E o ˆi cos (kz + ω t ) .
- (c)E r = – Eo ˆi cos (kz + ω t ) .
- (d)E = E ˆi sin (kz – ωt ) . r o
