Newton’s third Law
Field
Physical property that spreads out to a region of space and itdepends on the position and the time.
Electroestatic and Gravitational field Applied force per unit of the magnitud (charge,mass)
What about newton’s 3rd
Law?How many lines there are?
Electromagnetic waves?

Quantum field theory
One electron emits a photon and recoils; the second electronabsorbs the photon and acquires its momentum. This simpleprocess can be pictured with a Feynman diagram.
