What are the factors that affect signal propagation speed assuming no

1.	What are the factors that affect signal propagation speed assuming no noise?(a) Wavelength of the signal(b) Frequency of the signal(c) Strength of electrical and magnetic fields(d) Permeability and permittivity of mediumThis question was posed to me in an interview.Enquiry is from Types of Electronic Communication in division Introduction to Electronic Communication of Avionics
Answer» Correct option is (d) Permeability and permittivity of medium Explanation: SINCE the EM WAVES are made of electric and magnetic fields, the resistance GIVEN by the medium to conduct electric and magnetic waves DETERMINE the SPEED of the EM wave. This is given by the permeability and the permittivity of the medium.
