Why does the sun appear reddish early in the morning?
The sun appears reddish early in the morning because of the way that the atmosphere scatters sunlight. When the sun is low on the horizon, its light has to pass through more of the Earth’s atmosphere before it reaches our eyes. The atmosphere scatters short-wavelength light, such as blue and green, more than long-wavelength light, such as red and orange. So, when the sun is low on the horizon, the short-wavelength light is scattered away, leaving mostly red and orange light to reach our eyes, making the sun appear reddish.
Why does the sun appear reddish early in the morning? 3 Reasons
Scattering of light: The sun appears reddish early in the morning because the light from the sun has to travel through more of the Earth’s atmosphere before reaching our eyes. The atmosphere scatters blue light more than red light, which makes the sun appear more reddish.
Angle of incidence: The angle at which the sun’s light reaches our eyes is also a factor in the appearance of the sun. The sun is low on the horizon early in the morning, which means that the light has to travel through more of the atmosphere before reaching our eyes. This further scatters the blue light and makes the sun appear more reddish.
Rayleigh scattering: The sun’s light also has to pass through more of the Earth’s atmosphere early in the morning, which causes Rayleigh scattering. This is a phenomenon where the light is scattered by particles in the atmosphere, such as gases and tiny droplets of water. Rayleigh scattering is more likely to scatter blue light than red light, which makes the sun appear more reddish.
