Physics - EM Waves Question with Solution | TestHub

The wavelength is$5.4 \mathrm{m}$.

The frequency of electromagnetic wave is$54\times {10}^4 \mathrm{Hz}$.

The transmitted wave will be
$3.1\cos \left[\left(1.8\right)z-\left(5.4\times {10}^6\right)t\right]\hat{\mathrm{i}} \mathrm{N}/\mathrm{C}$.

The reflected wave will be
$3.1\cos \left[\left(1.8\right)\mathrm{z}+\left(5.4\times {10}^6\right)t\right]\hat{\mathrm{i}} \mathrm{N} {\mathrm{C}}^{-1}$.
