The velocity of an electromagnetic wave with frequency 6MHz and a skin

1.	The velocity of an electromagnetic wave with frequency 6MHz and a skin depth of 1.6 μm.(a) 3.75(b) 0.26(c) 9.6(d) 7.8The question was posed to me by my school teacher while I was bunking the class.Origin of the question is Lossless and Distortionless Line topic in division Transmission Lines of Electromagnetic Theory
Answer» The correct option is (c) 9.6 To elaborate: The VELOCITY of a wave is the PRODUCT of the FREQUENCY and the skin depth. It is given v = F. δ. On substituting for f = 6 x 10^6 and δ = 1.6 x 10^-6, we GET v = 6 x 10^6 x 1.6 x 10^-6 = 9.6 units.
