There are 5 lessons in this physics tutorial covering Electromagnetic Wave Packet. The Uncertainty Principle. The tutorial starts with an introduction to Electromagnetic Wave Packet. The Uncertainty Principle and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Electromagnetic Wave Packet. The Uncertainty Principle. you can access all the lessons from this tutorial below.
In this Physics tutorial, you will learn:
- What is a wave packet? What are its properties? Why is it used for?
- What does a light wave packet represent?
- What is the spatial extension of wave packet?
- What is the uncertainty relation for photons?
- What does the uncertainty of wave number represent?
- What is the uncertainty principle of Heisenberg?
- What is De Broglie's Wave Packet?
- What are the two mathematical expressions of Heisenberg's uncertainty principle?
Introduction
As we know, photons have a very high frequency (visible light oscillates in the range of 1014 Hz). In addition, we have explained in other articles that photons are produced when electrons move inside atoms from one layer to another. Do you think it is easy to determine the position of photons at a given instant? Why? What about momentum and energy? Can we be sure of the value of energy and impulse of a particle at a given instant?
What do you understand with "packet"? When do you use packets in daily life?
Besides providing answer to the above questions, this tutorial will unveil the limits of science in certain aspects, especially in measurements. The processes in micro-world do to work in the same way as in macro-world, so this is a point to highlight in this tutorial.
