The velocity of electromagnetic radiation in a medium of permittivity ε₀ and permeability μ₀ is given by
Options
(a) √(ε₀ / μ₀)
(b) √(μ₀ ε₀)
(c) 1 / √(μ₀ ε₀)
(d) √(μ₀ / ε₀)
Correct Answer:
1 / √(μ₀ ε₀)
Explanation:
The velocity of electromagnetic radiation in a medium of permittivity ε₀ and permeability μ₀ is equal to 1 / √(μ₀ ε₀).
