Can you guys recall what is the colour of the "Moon" of yesterday night?
The "Moon" will appear more orange and yellow when it first rises at night due to the earth's atmosphere.
Similar to why sunset is red, the orange colour is caused by the scattering of light by the atmosphere.
As compared to the moon directly overhead, the moonlight needs to pass through more atmosphere when it is nearer to the horizon.
Blue, green and purple pieces of visible light are scattered away by air molecules resulting us seeing only yellow, orange or red.
An orange coloured moon can appear at any time of the year sometimes even when it is directly overhead. This occurs when there is lots of dust, smoke or pollution in the atmosphere. The colour of the moon is determined by the size of these paticles.
Take a look at the moon on a hazy night. What colour moon will you see? ...
Ever wonder why the sky is blue and sunset is red?
The blue color is due to Rayleigh scattering. As light moves through the atmosphere, longer wavelength lights (red, orange and yellow) passes through.
Shorter wavelength lights is absorbed by the gas molecules in the atmosphere . The absorbed blue light is then radiated in different directions and get scattered all around the sky. Since blue lght is everywhere, the sky appears blue. The color of the sky nearer to the horizon appears paler or white.
As the sun begain to set, light must travel farther through the atmosphere. More light gets reflected and scattered. As less light reaches our eyes, the sun appears less bright changing its color slowly from orange to red as more short wavelength light (blues and greens) get scattered out. Only longer wavelength lights are left in the direct beam that reaches our eyes and the sky appears red, pink and orange.
Have a great day ahead! Adios!!! ...
