Chapter 12: Q1CE (page 558)

Explain to your friend who has just completed a study of classical electromagnetism, the term field Quantum.

Short Answer

Expert verified

When we learn about the electromagnetic field, it is a medium for particles to interact with each other. In modem physics, we explained this force as mediated by photon, an excitation of the electromagnetic field. The theory that explains photon is explained in the field quantum

Step by step solution

01

Given data 

The electromagnetic force, electromagnetic field, and electromagnetic wave.

02

Definition of Electromagnetic field

Electromagnetic field: when a charged particle moves from one point to another, it generates an electromagnetic field.

A stationary charge will produce only an electric field that will affect the other charges that are in its vicinity.

03

Explanation of Field Quantum

In classical electromagnetism, we learned about electromagnetic force, electromagnetic field, and electromagnetic wave.

When we learn about the electromagnetic field, it is a medium for particles to interact with each other.

In modem physics, we explained this force as mediated by photon, an excitation of the electromagnetic field.

The theory that explains photon is explained in the field quantum.

You are a promising theoretical physicist who does not believe that gravity is a distinct fundamental force but is instead related to the other forces by an all-encompassing relativistic, quantum-mechanical theory. In particular, you do not believe that the universal gravitational constant G is really one of nature's elite set of fundamental constants. You believe that Gcan be derived from more-basic constants: the fundamental constant of quantum mechanics, Planck's constanth ; the fundamental speed limiting the propagation of any force, the speed of lightc ; and one other- a fundamental length l, important to the one unified force. Using simply dimensional analysis, find a formula for G, and then an order-of magnitude value for the fundamental length.

To show that the Klein-Gordon equation has valid solutions for negative values of E, verify that equation (12-4) is satisfied by a wave function of the form .ψ(x,t)=Ae±ipx/ℏ±iEt/ℏ

To produce new particle accelerators often smash two equal mass objects together proton and proton or electron and positron. The threshold energy is the kinetic energy before the collision needed simply to produce the final particle their mass thermal energy alone with no leftover kinetic energy. Consider a colliding beam accelerator in which two initial particles of mass m are moving at the same speed relative to the lab. Assume that the total mass of the stationary particles after the collision is M. Show that the threshold energy is M-2mc2.

Why would it be argued that the range of the strong force should be infinite, and why it isn’t?

The electron mentioned in Section 12.3 for deep inelastic scattering experiments is20GeV , and the momentum is given as .20 GeV/c Why so simple a conversion?
