Question:medium
Electromagnetic waves travel in a medium with speed \( 1.5 \times 10^8 \) m/s. The relative permeability of the medium is \( 2.0 \). The relative permittivity will be:
Electromagnetic waves travel in a medium with speed \( 1.5 \times 10^8 \) m/s. The relative permeability of the medium is \( 2.0 \). The relative permittivity will be:
Show Hint
The speed of light in any medium is given by \( v = \frac{c}{\sqrt{\mu_r \varepsilon_r}} \), where \( \mu_r \) and \( \varepsilon_r \) are the relative permeability and permittivity.
