Chapter 14: Riding The Wave Function

According to experts in physics, light can either be a particle or a wave. Here is how we decided that light is either a particle or a wave.

Light as a wave

Light can be labeled as an electromagnetic wave in that a changing electric field forms a changing magnetic field. In turn, the changing magnetic field further creates a changing electric field, and that is what is simply termed as light.

In contrast with many other waves like water and sound waves, light does not require a medium to wave in.

Light as a particle

Some scholars have come up with the notion that light is also a particle. Light can be seen as individual things, and this makes for particles.

In summary, light a particle or a wave is one challenging question that answer is not definite. In some circumstances, light can act as a particle, while in other circumstances, light actually acts as a wave.

Meanwhile, some things may go wrong with the assumption that light is either a particle or a wave.

Here are some of the points that illustrate that there is something wrong with both assumptions:

Gravity: The gravitational force model works when it is close to the surface of the planet earth.

Momentum: This is another point showing something wrong with light being either a particle or a wave. At lower speed, the model of non-relativistic and better momentum works together. However, if the proton goes way fast, both the better and non-relativistic models will no longer work out.

What is a wave function?

A wave function is referred to as the function that shows the chance of a particle’s quantum state as a function of time, spin, momentum, or position.

The variable commonly knows wave functions.

Furthermore, a wave function can be used to show the chance of discovering or locating an electron within a matter-wave. The wave function, which has an imaginary number, is always squared to produce a correct number solution to carry this out.

Also, the chance of an electron staying within a particular position can then be checked. The wave function was brought into existence by a well-known scientist known as Erwin Schrodinger in 1925.

What’s more? Wave function carries vital information that concerns the electro and its link with the wave function and how we get the angular momentum, orbital orientation, and the electron’s energy.

Additionally, the wave function can either be negative or positive. The negative or positive sign is crucial when calculating. In fact, it is also vital whenever the wave functions of two or more atoms join together to create a molecule.

The wave functions that have similar signs will interfere constructively, resulting in the chance of bonding. On the other hand, the wave functions that do not have similar alerts will interfere destructively.

Due to Schrodinger’s equation, scientists were then suitable to know the wave functions for electrons in molecules and atoms.

Initially, many scientists thought the wave function represented where a photon (or another particle) is spread along with its wave. For example, they thought that perhaps 60% of a photon's energy is in one spot, plus 30% adjacent, and 5% a bit farther, etc.
