An electromagnetic wave of frequency 5GHz, is travelling in a medium whose relative electric permittivity and relative magnetic permeability both are 2. Its velocity in this medium is _______ 10^7m/s.

Question

Accepted Answer

Correct answer: 15. (15) Given: f=5 GHz _r=2 _r=2 Velocity of wave ⇒v= cm … (i) Where, n= _r _r and c= speed of light =3 10^8 m/s n= 2 2=2 Put the value of n in we get ⇒v= 3 10^82=15 10^7m/s ⇒X 10^7=15 10^7 X=15

$An electromagnetic wave of frequency 5GHz, is travelling in a medium whose relative electric permittivity and relative magnetic permeability both are 2. Its velocity in this medium is _______\times 10^{7} m/s.$
