That the electric field is uniform between the electrodes means that the electric field lines: A. are more closely spaced at the positive electrode than at the negative one. B. intersect halfway between the electrodes. C. are more closely spaced at the negative electrode than at the positive one. D. are equally spaced at both electrodes and between them.

Option D.

Are equally spaced at both electrodes and between them.

Explanation:

An electric field is the region that surrond electrically charged particle which may cause attraction or repelling of the particle due to the force that is exerted on it.

The electric field between two electrodes due to electrostatic forces exist in the air and there is an increase of external voltage is added to it. Electric field are uniform between electrodes which signify that the electric field lines are evenly spaced at both electrodes and between them.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
