Question
What is the velocity of electromagnetic wave in a good conductor ?(A) $3 \times 10^{8} \mathrm{~m} / \mathrm{s}$(B) more than $3 \times 10^{8} \mathrm{~m} / \mathrm{s}$(C) High(D) Very low
Step 1
Step 1: The velocity of an electromagnetic wave in a good conductor is given by the formula: \[v = \frac{1}{\sqrt{\mu \epsilon}}\] where \(\mu\) is the permeability and \(\epsilon\) is the permittivity of the conductor. Show more…
