Objects that emit light and illuminate their surroundings are light sources. The biggest light source that illuminates our world is the Sun. Natural light sources are sources that can emit light spontaneously. The Sun and the stars in the structure of the Sun are natural light sources. The light we see during a lightning strike or lightning strike is also a natural light source. Some living things can even produce their own light. Fireflies, jellyfish, cuttlefish, and some fungi are also natural light sources. Today, we will answer questions such as what natural light sources are and why we need them.
We can say that everything we see around us is due to light. lights natural and artificial is divided into two. In this article, we will talk about natural light sources. If a light can be seen with the human eye, the electromagnetic radiation frequency of that light 390 to 700 nanometers is around. The Sun, which rises in the east every morning and sets in the west every evening, both illuminates and warms the earth throughout the day. He is our main is our natural light source. Lightning and lightning, with their sudden bright lights and the loud noise they create, have always brought people to life. frightened. Lightning is actually a very strong electrical current that lasts less than a second.
Just as the electric current passing through the filament of a light bulb turns the filament incandescent and illuminates the environment, so does the electric current between the cloud and the ground. a natural light source illuminates the environment. If you look at the sky from a place where the city lights are not visible on a cloudless night without the moon, thousands of your star You see it winking at you. Within a few minutes, your eyes will get used to the darkness. The Milky Way stretches from one horizon to the other in all its glory. All the stars you see are just like the Sun. natural light is the source.
What are natural light sources?
sunlight
The sun is for our planet most important natural light one of the sources. It is a gigantic energy producing huge energy with nuclear fusion at its center. fireball is defined as. This energy from the sun comes out in the form of light and heat. on our planet sustainability of life The biggest factor behind it is natural light from the Sun.
Lightning and lightning
Lightning is caused by a charge imbalance between the ground and the clouds. electric is the current. Negative charges in the clouds, namely electrons, try to be attracted towards the positive charges on the earth, namely protons. This is lightning, so a electrical current creates. It would be nice if we could store this energy, but it is not possible to store it yet in today’s technology. Meanwhile, lightning is like lightning, but between two clouds. load imbalance is the resulting electric current. Both are natural light sources.
animals
Some deep sea creatures such as Fireflies, Jellyfish, Anglerfish, Viper fish glow in the dark. When these creatures want, chemical energy can be converted into light energy. To such creatures bioluminescent called live. These animals are also considered to be prime examples of natural light sources.
plants and fungi
Various plants, even fungi, can emit light by transforming the chemicals they contain. These plants and fungi bioluminescence It’s called live. Contents caffeic acid they turn it into a compound that provides luminescence, and in this way, they can naturally illuminate the environment in the dark. That’s why plants and fungi are among our natural light sources.
insects
Many insects such as fireflies and glowworms also tend to emit natural light. Fireflies use the light they produce against their enemies. defend oneself and communicate uses for. Interestingly, fireflies do not feel heat due to the light they produce. Because the light they produce is different from normal light. Scientists produce this light cold light gives its name. Such insects are also among our natural light sources.
stars
Some reactions take place inside the sun and other stars, that is, in their cores. to these reactions fusion reactions and stars produce energy in this way. This energy rises to the surface and radiating into space emitted as visible light. The light that reaches our eyes is a tiny fraction of the energy produced by stars. Most of the high energy infrared or ultraviolet propagates at wavelengths. That’s why stars are also our natural light sources.
So what is the importance of natural light sources for us?
Our ancestors did not have artificial light sources. All civilizations for thousands of years sunlight Thanks to this, he saw his way ahead, and some civilizations even worshiped the sun. Presumably until the time we live in, natural light sources the benefit, the importance No one thought to speak. But come on, we are currently dependent on artificial lights. However, the benefits of natural light sources for us do not end with counting, therefore natural light sources are the best for us. is of great importance. Exposure to natural light source Vitamin D helps produce. It helps us sleep and focus. It has a huge impact on our physical and psychological health.
By the way, sunlight does not give us vitamin D directly. It activates the enzymes that produce vitamin D by penetrating under our skin, and our body begins to produce vitamin D. in the absence of depression, obesity, multiple sclerosis cause diseases such as We all need to be productive, so we should take advantage of natural light sources. One of the biggest benefits of natural light is that it makes us more productive. In particular, employees who benefit from sunlight in their workplaces more hardworking and productive somehow doing their job. At the same time, we start to feel better psychologically. Not being able to take advantage of the sunlight depressed, depressed It can even make you feel anxious. For example, that’s why Seasonal Affective Disorder There is also a disease called
In this article, we have looked at the natural light sources in detail, we have examined and learned why we need them. Although we do not like the sun, which is our biggest natural light source, because it causes us to suffer in summer, it is actually a great source of light for us. of great importance we saw that. In order to benefit from the sunlight during the day, you should go out and walk and breathe the fresh air.
