Maxwell: -"The ratio of m to mu varies in different substances; but in a medium whose elasticity depend entirely upon forces acting between pairs of particles, this ratio is that of 6 to 5, and in this case E^2= Pi*m"

Q1: What is this 6:5 ratio and how did he make that conclusion?

Q2: What is the importance of "depend entirely... pairs of particles"?

Maxwell: -"To find the rate of propagation of transverse vibrations through the elastic medium, on the supposition that its elasticity is due entirely to forces acting between pairs of particles

where 'm' is the coefficient of transverse elasticity, and 'p' is the density."

Q3: Again this "entirely due to pairs of particles", what is he talking about, is he saying photons are made of particle pairs, or is he describing aether as something like Dirac Sea made of electron-positron pairs, or what?

Q4: Where did he get numerical values for this elasticity 'm' and density 'p', are those two the same numbers as electric and magnetic constant in modern equations?

Q5: Did anyone notice his original "wave equation" is nothing else but the 'wave equation for vibrating string': -"The speed of propagation of a wave in a string (v) is proportional to the square root of the tension of the string (T) and inversely proportional to the square root of the linear mass (μ) of the string:
