It’s a fact that people travel thousands of miles to have a best sunset view. Apart from the setting aspect signifies the end of the day, the beauty of its reddish-orange which makes the whole atmosphere and the moment so adorable is unbeatable. Let’s find out what makes it look reddish orange to our eyes when the sun sets.
The color that we can see depends on the frequency of the emitted light. Different frequencies of light are perceived in different colors, and Red has the lowest frequency. Most objects exhibit reflection rather than emit light, and they reflect only a part of the light that is shining on them which gives them their color. An apple appears red in white light because it reflects the red part of the white light. If you try looking an apple through a prism to generate a spectrum, you can notice the color of an apple is changing.
The Sun emits white light, and it’s a composition of all the visible frequencies. Red, orange and yellow light have lower frequencies when compared to blue and green. All these low-frequency lights are scattered the least by nitrogen and oxygen in the atmosphere. Therefore, red, orange and yellow light are transmitted through the Earth’s atmosphere more quickly than blue. Red scatters the least amount when compared to all the other colors. This implies that we do not see the effects of reflection, but the consequences of emitted and transmitted light.
That’s the reason when we see a setting Sun, a white-light emitting object, through the thick atmosphere of Earth. Higher frequencies are scattered, and lower frequencies are transmitted. At the Sunset, the Sun is lowest in the sky and seen through a large amount of air mass, we enjoy it in reddish orange color.
