MCQ
The electromagnetic wave travelling in a medium has relative permeability 1.3 and relative permittivity 2.14. The speed of EM wave in that medium will be
  • A
    $13.6 \times 10^6 m / s$
  • B
    $1.8 \times 10^6 m / s$
  • C
    $3.6 \times 10^8 m / s$
  • ✓
    $1.8 \times 10^8 m / s$
✓

Answer

Correct option: D.
$1.8 \times 10^8 m / s$
(D) $1.8 \times 10^8 m / s$
$v=\frac{c}{\sqrt{\mu_0 \varepsilon_0}}=\frac{3 \times 10^8}{\sqrt{1.3 \times 2.14}}=1.8 \times 10^8 m / s$
