Electromagnetic Waves - Result Question 13
13. The velocity of electromagnetic radiation in a medium of permittivity $\varepsilon_0$ and permeability $\mu_0$ is given by
[2008]
(a) $\sqrt{\frac{\epsilon_0}{\mu_0}}$
(b) $\sqrt{\mu_0 \in_0}$
(c) $\frac{1}{\sqrt{\mu_0 \in_0}}$
(d) $\sqrt{\frac{\mu_0}{\epsilon_0}}$
Show Answer
Answer:
Correct Answer: 13. (c)
Solution:
- (c) The velocity of electromagnetic radiation in a medium of permittivity $\epsilon_0$ and permeability $\mu_0$ is is equal to $\frac{1}{\sqrt{m_0 \hatI_0}}$.
