A linearly polarized electromagnetic wave in vacuum is
$\mathrm{E}=3.1 \cos \left[(1.8) \mathrm{z}-\left(5.4 \times 10^6\right) \mathrm{t}\right] \hat{\mathrm{iN}} / \mathrm{C}$
is incident normally on a perfectly reflecting will at z = a. choose the correct option
Select the correct option:
A
The wavelength is 5.4 m
B
The frequency of electromagnetic wave is $54 \times 10^4 \mathrm{~Hz}$.
C
The transmitted wave will be $3.1 \cos \left[(1.8) z-\left(5.4 \times 10^6\right) t\right] \hat{i} \hat{N} / C$
D
The reflected wave will be $3.1 \cos \left[(1.8) \mathrm{z}+\left(5.4 \times 10^6\right) \mathrm{t}\right] \hat{\mathrm{iN}} / \mathrm{C}$
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Reflected wave will have direction opposite to incident wave.
