Black Body Radiation: A Phenomena which change physics forever

Introduction:

In the beginning, classical physics was able to predict everything accurately and we are heavily dependent on it for everything. But it said that nothing is perfect. Likewise, the case of classical physics which fails to explain certain phenomena. The one such case that classical physics can't explain is "BLACK BODY RADIATION".

It is said that everybody emits electromagnetic radiation above absolute zero. But scientists are very curious. They try to imagine a body that emits every wavelength of electromagnetic radiation or absorbs every kind of wavelength. This body was called "BLACK BODY".

Point to be noted:

There is one point that you must keep in mind:

1. In this universe no perfect black body is present.

Example:

Let's imagine a bulb with a platinum filament if we increase the voltage temperature of the filament increase and when the temperature of the filament reaches 500 degrees Celsius the wire becomes dull red, if we increase the temperature up to 900 degrees Celsius then its color become cherry red and so on to white at 1600 degree Celsius.

This is also related to the black body; by this, we can predict the temperature of any star by observing the color it emits. 

How cool right!

Explanation of Classical Physics and the Beginning of Quantum Physics:

According to classical physics objects that have temperatures up to higher than a certain limit emit an infinite amount of energy. This is also known as an "ultraviolet catastrophe".

To explain this Max Plank came and solved this by assuming that light is not in continuous form but travels in the discontinuous form. And by this, he proves the curve accurately.

This is the moment by which the rise of quantum physics began and this thing changed the civilization of humanity completely.

By quantum physics, we explain many mysteries and due to this, our technology improve. Science is really beautiful in all the things that humanity has because it becomes perfect with time. In the era of Quantum physics, humanity changed completely and with this increasing amount of knowledge, we built quantum computers and much more technology soon like quantum internet.

Black body radiation is a significant phenomenon that increases our understanding of the universe and revolutionizes our technology. Black body radiation helps us to understand quantum physics and is also very useful in cosmology and in-camera like thermal cameras.

In Cosmology:

In cosmology, scientists and astronomers can predict the energy of a star, its temperature, and so many details.

For example, cosmologists with the details of which wavelength stars emit predict their temperature, luminosity, and power by the equations of the black body.

In technology:

In technology, the knowledge of the black body helps us to understand many things by which we built thermal cameras, infrared thermography, medical imaging, temperature sensors, and many more such things.

Conclusions:

Black body radiation is a critical phenomena in physics that change the whole world of physics and science completely. That is why we built such power devices that can measure the temperature and other factors of stars at great distances accurately.

I have a question for you.
Think about that what is the total energy of the universe?
