A uniform plane wave with electric field 
is travelling in the air (relative permittivity, 
and relative permeability, 
) in the 
direction (
is a positive constant, 
is the unit vector along the 
axis). It is incident normally on an ideal electric conductor (conductivity, 
) at 
. The position of the first null of the total magnetic field in the air (measured from , in metres) is
Explanation:
At perfect conductor,
We know that 
occurs at 
Hance, 
So,
So, for 1st value of 
for H-field to be zero
Now, form equation
Hence 
If the reference is not at interference, then
