The electric field vector of a plane electromagnetic wave oscillates sinusoidally at a frequency of $4.5 × 10^{10} Hz$ in a medium with permittivity to and permeability $μ_0$. The wavelength of the wave is |
$6.67 × 10^{-4} m$ $2 × 10^{-3} m$ $6.67 × 10^{-3} m$ $6.67 × 10^{-12} m$ |
$6.67 × 10^{-3} m$ |
The correct answer is Option (3) → $6.67 × 10^{-3} m$ |
