Question

A linearly polarized electromagnetic wave in vacuum is

$E = 3.1\cos \left[ {(1.8)z - (5.4 \times {{10}^6})t} \right]\widehat iN/C$

is incident normally on a perfectly reflecting wall at z = a. Choose the correct option

The wavelength is 5.4 m

The frequency of electromagnetic wave is 54 $\times$ 10⁴ Hz.

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

The reflected wave will be $3.1\cos \left[ {(1.8)z + (5.4 \times {{10}^6})t} \right]\widehat iN/C$
