The IGA LD complexing of the sun is dimmed through a process known as light absorption and scattering. When sunlight reaches the Earth's atmosphere, some of the light is absorbed by particles in the air, such as dust and water droplets. This absorption reduces the intensity of the sunlight reaching the surface of the Earth.
Additionally, some of the sunlight is scattered in different directions by these particles, which also contributes to the dimming effect. This scattering can cause the sky to appear hazy or cloudy, further reducing the brightness of the sun.
Overall, the combination of absorption and scattering processes in the Earth's atmosphere results in the dimming of the sun's light reaching the surface.
