Did you know that sunlights are also some types of lights? Also, all colors are made out of lights. Lights make us see the colors and make things bright. If there are no lights in this world, the world will be covered with darkness.

Light What Is Light? Light: We can see some types of light but there are other types of light that we cannot see. This electronic radiation is a radiation that carries radiation energy. And the light that we can see is usually explained as wavelength. Also, wether the lights are visible or not, it can be in any wavelength. Lastly, the light’s speed is 299,742,258 meters per seconds. The Light has particles and waves. To look at this, you can change magnetic fields and electric in space that are propagate creating an electromagnetic wave. The Light has particles and waves.
This wave have amplitude that is brightness of the light wavelength is the one that have the color and angle that vibrate called polarization. Light is mysterious and obvious. Lights stave off the darkness with fluorescent and incandescent bulbs. When sunbeam angles go through the room that is filled with dust, we can see glimpses of light’s nature. Light appears when a rainbow comes out after a storm.
This is Light coming out from clouds.

How It Works How do Lights work?
Incandescent bulb works by heat caused by an electrical current that passes through a wire. The filament or a wire gets so much heat that it makes light. Filaments are made of tungsten that we use every day. Because that hot tungsten can burn away quickly if it is exposed to oxygen so it
needs to be put in sealed glass which is evacuated or fill with gas that will not let it burn. Lights travels in straight lines.

Uses How are Light Used?
Electrons are able to combine again releasing energy in form of photons when a light emitting diode is turned on. This process is called electroluminescence and the color of the light is decided by the band gap of the energy semiconductor. LED is one of the small area and made in small parts in shape of radiation pattern.
LEDs have a lot advantages in incandescent light kinds including lower energy, longer lifetime, developed robustness, small size and faster switching.

Types What are some types of lights?
An electric light is a device that makes lights for the flow of electric current. This electric light is the most common light that are needed in society and for giving interior light for buildings and more lights for afternoons activities. The most electric lightning is controlled by generated electric power but lighting can also be controlled by mobile or electric generators or some battery things. Things those are used in batteries
are usually called flashlights or torches. The two main things of electric lights are incandescent lamps which are give off lights by filament heated hot by electric current and lamps that are discharged gas which we produce light by an electric through gas.

I, Sunny Kwon the Author wrote this book because we use lights a lot these days. I go to school called S.A.S in 5-PT. I am korean but I started to live in shanghai when I was 6 years old. If you have questions, send it to my email: < sunny01px2021@sasstudent.org >
