Answer:
The electric field is 
and the ditection is from outer to inner side of the membrane.
Explanation:
We know the electric field (
) is given by 
, 'V' being the potential.
In 1-D, it can be written as
where 'd' is the separation of space in between the potential difference is created.
Given, 
and the thickness of the cell membrane is 
.
Therefore the created electric field through the cell membrane is

Sound waves are known to be the one that's not considered as a type of electromagnetic energy. As for microwaves and x-rays, they tend to share the same frequencies that can be considered as electromagnetic, and sound waves have a different frequency than them.
