WHAT COLOR IS THE SUN REALLY?

The sun emits light in a wide range of wavelengths (or colors). In fact, it does so in all parts of electromagnetic radiation, except gamma rays. The maximum amount of the Sun's spectrum can be used to determine its surface temperature, approximately 5,780 Kelvin (approximately 5,500 ° C). The same process can be used to find higher star temperatures.

The maximum length is on the screen and usually determines the color of the visible object. So, for example, cool stars appear red and hot stars appear blue, with orange, yellow, and white stars in the middle. On the Sun, the spectrum actually rises to the level of a scale that is often described as green.

However, beyond the small width of the visual display, the amount of light emitted from the length of each area is almost exactly the same. But most importantly, the human eye does not detect light by measuring different colors of the spectrum together. Therefore, the slightest excess of green light does not look green in the human eye - it looks white. The Sun should emit only green light so that our eyes can see it as green.

This means that the actual color of the Sun is white. So, why does it usually look yellow? This is because Earth's atmosphere reflects blue light far better than red light. This slight deficiency in blue light means that the eye sees the Sun color yellow.

As the sun's rays pass, the blue light spreads more and more. Therefore, at sunrise and sunset, there is a very high percentage of red light in the Sun's spectrum, which gives generally impressive results.
