        Wave-Particle Duality

In quantum physics, wave-particle duality is the most basic concept where its principle says that particles in other words photons and electrons behave like a wave where waves can behave like particles, or sometimes electrons can behave like particles or waves, depending on how they are observed. Pretty confusing right? You can see the figure below for clarity.

For example, if you are a student of quantum physics, you have probably heard about the double slit experiment, it is a well-known demonstration of wave-particle duality This entails launching particles like electrons through a wall that has two tiny slits. The interference pattern that the particles make on a screen behind the barrier as they go through the slits suggests that they behave like waves. The interference pattern, however, vanishes when the experiment is viewed, and the particles resume their normal behavior.

The Uncertainty Principle

The uncertainty principle is a key notion in quantum physics that reflects our inherent constraints in accurately measuring certain physical characteristics of particles. According to the uncertainty principle, it is impossible to simultaneously know a particle's precise position and momentum.

Fig: Uncertainty Principle

The uncertainty principle is represented mathematically as follows:

ΔxΔp ≥ h/2π

where x represents location uncertainty, p represents momentum uncertainty, and h represents Planck's constant. As a result, one may estimate a particle's momentum with less accuracy the more precisely one can detect a particle's location, and vice versa. In other words, there is a trade-off between position and momentum measurement precision.

The behavior of particles at the subatomic scale is significantly affected by the uncertainty principle. This implies that particles cannot be explained in terms of classical objects and that probability theory governs their activity. The energy preservation hypothesis is a basic concept that distinguishes quantum physics from classical mechanics.

Quantum Entanglement

The term “quantum entanglement” is another fascinating concept in quantum physics. It explains the phenomena in which two particles get entangled and their characteristics become inextricably connected, which means if you are able to measure the properties of one particle, immediately you knew the properties of another particle, it doesn’t matter how far apart those two particles are.

Let's take a closer look with an example.

 Real-World Examples of Quantum Physics

And now let's discuss a few applications of quantum physics in the actual world. One of the most popular examples is the laser, which exploits Quantum Mechanics principles to generate a highly concentrated beam of light. Lasers are employed in a variety of applications, ranging from CD players to surgery.
