I WONDER IF WE CAN USE A STRONG PULSES OF ELECTROMANETIC WAVE TO DESTROY MISSLESS IN THE AIR.
IF WE KNOW THE LENGHT AND THE DIAMITER OF THE MISSLE WE CAN CALCULATE THE RESONANCE FREQUENCY OF THE MISSLE AT WHICH IT WORKS AS AN ANTTENA.
IF WE CAN TRANSMITT TO THE AIR A STRONG PULSE OF E.M. WAVE WHICH MATCH THE RESONANCE FREQUENCY OF THE MISSLEWE IT
CAN CAUSE AN ELECTRIC CURRENT TROUGH THE MISSLE WHICH CAN CAUSE IGNITION OF THE EXPLOSIVE MATERIAL IN TT AND CAUSE THE EXPLOTION OF MISSLE WHILE THE MISSLE IS STILL THE AIR .

the resonance freq will be so low that teh waves would dissipate in strength by the time they reach the missile :)

in the lecture Bo=Eo/c
I don,t know... why?

i know as follows
Bo=Eo/η, η=root(μo/εo)=377(ohm)

please help me...

I mistake...

Bo=Eo/η, η=root(μo/εo)=377(ohm)(X)

so i think

Ho=Eo/η, η=root(μo/εo)=377(ohm)(O)
