The expression for velocity of a wave in the conductor is(a) V = √(2

1.	The expression for velocity of a wave in the conductor is(a) V = √(2ω/μσ)(b) V = √(2ωμσ)(c) V = (2ω/μσ)(d) V = (2ωμσ)The question was posed to me by my college director while I was bunking the class.My doubt stems from Plane Waves in Good Conductor topic in division EM Wave Propagation of Electromagnetic Theory
Answer» Right option is (a) V = √(2ω/μσ) Best explanation: The velocity is the ratio of the frequency to the phase CONSTANT. In conductors, the phase constant is given by √(ωμσ/2). On SUBSTITUTING for β,ω in v, we GET v = √(2ω/μσ) UNITS.
