Solve the all part of following problem given below:
Problem: A 250MW laser pulse is focused with a lens to a diameter of 1.0m.
Part I: What is the laser beams electric field amplitude at the focal point?
Part II: What is the ration of the laser beams electric field to the electric field that keeps the electron bound to the proton of a hydrogen atom? The radius of the electron's orbit is 0.053 nm.
Rework your solution from the beginning and check each step carefully. Thanks.
