The totally ecliped full moon is reddish in color due to the solar prominences. true or false
What do you think?
Consider the difference between eclipses of the moon and sun. The light that illuminates the moon during a total lunar eclipse comes from the entire solar disc, but that light is bent by the atmosphere of the earth before it gets to the moon.
Most light you see coming from the sun during a solar eclipse comes from the outer edge of the sun, where the prominences are.
I think it's false. I read somewhere that the reddish color is due to the Earth's athmosphere.
That is, the light does come from the sun but it's the Earth's atmosphere which lets the red part of the sun's light through.
At least, that's how I understood it.
E. G. is correct.
False.
The reddish color of a totally eclipsed full moon is not caused by solar prominences. Rather, it is a result of a phenomenon called Rayleigh scattering. During a total lunar eclipse, the Earth passes between the Sun and the Moon, casting a shadow on the Moon's surface. However, some sunlight does manage to pass through Earth's atmosphere and reach the Moon.
When sunlight passes through the Earth's atmosphere, the shorter blue and green wavelengths are scattered away by the gases and particles in our atmosphere. The longer red and orange wavelengths, on the other hand, are less affected by this scattering and tend to pass through. As a result, the light that reaches the Moon during a total lunar eclipse is mostly red in color.
So, the reddish color of a totally eclipsed full moon is due to the scattering of sunlight through Earth's atmosphere, not solar prominences.
