Calculate the attenuation constant of a conductor of conductivity 200

1.	Calculate the attenuation constant of a conductor of conductivity 200 units, frequency 1M radian/s in air.(a) 11.2(b) 1.12(c) 56.23(d) 5.62I got this question by my school principal while I was bunking the class.This is a very interesting question from Plane Waves in Good Conductor topic in division EM Wave Propagation of Electromagnetic Theory
Answer» CORRECT choice is (a) 11.2 Explanation: The ATTENUATION constant of a conductor is given by α = √(ωμσ/2). On SUBSTITUTING ω = 10^6, σ = 200 and μ = 4π x 10^-7, we get α = 11.2 UNITS.
