1.	Expression for refractivity is given by ___________(a) N=(n-1)×10^6(b) N=(n-1)×10^-6(c) N=1/(n-1)(d) N=\(\frac{1}{n-1}\)×10^-6The question was posed to me by my college professor while I was bunking the class.This question is from Space Wave Propagation in division Space Wave Propagation of Antennas
Answer» The correct option is (a) N=(n-1)×10^6 For EXPLANATION: REFRACTIVITY is to observe the CHANGE in refractive index due to the smallest change in the relative DIELECTRIC constant. N=(n-1)×10^6
