Light is an essential element for any life. The diversity we see around us is mainly due to this light. And our source of this light is the sun. You may be sitting in the sunlight on a winter morning and thanking Surya Mama in your heart. But did you know that light / You are thanking the sun for the heat It was created in the center of the sun about 1 million years ago today and you are enjoying the heat of the sun 1 million years ago today after 1 million years. Isn’t that a surprise? After reading a little from, the surprise is gone. In today’s article, we will know how the light of the sun that came to the earth today is 1 million years ago? After reading this article, I promise that your surprise will also go away. So let’s start-
You’ve probably heard of nuclear fusion reactions many times over. Nuclear fusion reactions are constantly taking place at the center of the sun, and these reactions produce the sun a temperature of 15 million degrees Kelvin and generate an enormous amount of energy that we can’t even imagine. Just as the heart must be present, so must the nuclear fusion reaction be in order for the sun to survive.
The structure of the Sun is divided into different regions: 1) Central Region 2) Radiation Zone 3) Circulation Zone The formation of the Sun in some other such regions. Spreads out.
The sun produces billions upon billions of energy every day at its center. This process has been going on for billions of years. The sun produces 560 million tons of helium per second, which requires 564 million tons of hydrogen. This energy produced in the center of the sun spreads outwards from the surface of the sun as photons.
The density of the center of the sun is 15 times greater than the density of water. Although the density of the outer region is gradually decreasing than that of the center of the sun. It still takes a lot of sun’s heat and energy to traverse this vast area. You would be surprised to know that a photon conjunctiva can traverse this region 1,71,000 years. It takes about 1 million years and from the surface of the sun at the same angle it takes us only 15 minutes.
Now do you realize how many years ago the heat of the sun that you are enjoying sitting on the earth right now originated in the center of the sun? And that’s why scientists say that if we look at our universe, all we can see is the past of this universe and What is happening now may be seen by our future generations. Today we will learn in detail in this article how these electromagnetic waves travel across this vast path and spread to the solar system.
The plasmas that surround the center of the sun have a much higher density. This is why gamma rays produced by fusion reactions are absorbed by electrons when they travel very short distances. These electrons then re-emit the absorbed gamma rays in all directions. When absorption and emission occur, some of the energy generated at the center is lost or lost. And after emission, this gamma ray enters the sun’s radiation zone.
The sun’s radiation region acts as a shield to the center of the sun. The fusion reaction is carried out by maintaining a temperature of 15 million degrees Kelvin created in the center of the sun. It has to be absorbed and emitted, which causes the photon particles to slow down and at the same time lose some of their energy, resulting in gamma rays being converted to X-ray rays.
The photons produced in the center of the sun are transported through the radiation zone of the sun in the process of thermal transport. The sun’s radiation zone is filled with hydrogen, helium, and unsaturated electrons. In the deepest part of the sun’s radiation zone, X-rays collide with different particles. As a result of two collisions, X-ray particles can travel only a few millimeters.
In this way, the X-ray rays travel through the sun’s radiation and other regions to the surface of the sun. It takes 181,000 years to 1 million years for a photon corner to cross this path. The energy of the X-rays is absorbed by the plasma. As it decreases, the wavelength increases. Gradually, the wavelength of this X-ray increases and at one time the X-ray turns into light. As it turns into light, the temperature generated in the center changes from 15 million degrees Kelvin to 1.5 million degrees Kelvin.
The radius of the region around the Sun’s radiation zone is 30% of the radius of the Sun. And this region is the last layer inside the Sun. And the temperature and density of this region of the Sun are less than the radiation region of the Sun. ) With the help of gaseous molecules it receives radiated heat from the radiation zone. As it receives heat through gaseous molecules, the temperature rises. At this time these gaseous molecules swell like balloons and their density decreases. Began to move in that direction.
When these gaseous molecules move out of the convection zone, they are cooled by radiation of heat.
This process of heat transfer is a lot like the boiling of water where bubbles are formed. This process of bubble formation is called granulation process.
Gamma rays are the smallest waves in the electromagnetic spectrum. And because of this smallness, gamma rays become much stronger. And this gamma ray is generated from the center of the sun and travels through different regions of the sun to become light. When you look at the sun we see the sun We can see the region because it reflects light produced by gamma rays. Gamma rays are generated in the center of the sun, come to this level, collide with different particles or are absorbed by electrons, lose their energy and lose energy, causing its wavelength to increase. As the wavelength increases, visible light is obtained from the sun.
