is it possible for an object to have product of relative permittivity & permeability < 1
velocity of light in a medium is given by
v = (1/0
0)
where one epsilon & mu are for absolute value & anuther for relative value.
putting value of 0
0,
v = c/
if product of these two are less than one, velocity in that medium 'll be more than velocity of light.
so please say is it possible that =1.5 &
= 0.5 for a particular medium.
