1.	The depth of penetration of a wave in a lossy dielectric increases with increasing(a) Conductivity(b) Permeability(c) Wavelength(d) PermittivityI have been asked this question in an internship interview.Query is from Advanced and Tricky Questions in chapter Advanced and Tricky Questions of Electromagnetic Theory
Answer» CORRECT choice is (c) WAVELENGTH Easy explanation: The DEPTH of penetration or skin depth is inversely proportional to the frequency. THUS it has to be DIRECTLY proportional to the wavelength.
