Lightning strikes - safe in car, but...
Hii 2 all,
I am new here, and this is my first.
We all know that when a lightning strikes one is very safe inside a car.
Coming to my Q.
Gauss law states, Charges Resides on the outside of a conductor. Fine.
Applying the same to a car, a car acts like a Faraday cage allowing no charges to the inside from outside. Great.
But...
My car is NOT a perfect conductor. There are a lot of "UnConductory" things within my car. Now the lightning should be able to find its way inside.
From a quick search in google... I came across one reason with no explaining to it.
Reason being Wavelength !
here is my source (part 3)

Would be gr8 if someone cud explain why?
