The continuity of the tangential field component at the interface of two media for normal incidence of a plane wave requires
- A. $T=1-\Gamma$
- B. $T=1+\Gamma$
- C. $T=\Gamma$
- D. $T\neq\Gamma$
Answer: B. $T=1+\Gamma$
Explanation: At the boundary interface, the sum of the incident and reflected tangential electric fields equals the transmitted field: $E_{inc} + E_{ref} = E_{trans}$. Dividing by $E_{inc}$ gives $1 + \Gamma = T$.
