Using = 𝛍^0 H find the ratio E^0/H^0 for a plane electromagnetic wave propagating through vacuum. Show that it has the dimensions of electric resistance. This ratio is a universal constant called the impedance of free space.

Question

Deepak Patra · Answer

Sol. E = Q/ϵ base 0 A (Electric field) ∅ = E.A. = Q/ϵ base 0 A A/2 = Q/ϵ base 0 2 i base 0 = ϵ base 0 d∅ base E/dt = ϵ base 0 d/dt (Q/ϵ base 0 2) = 1/2 (dQ/dt)
