Why is the moon red during an eclipse? Isaac Kua

The redness is caused by the light of sun shining through Earth's atmosphere. Partially it is due to the way light is scattered, meaning reddish light reaches the moon. We get similar effects at sunset. Also there is a lot of dirt and dust in the Earth's atmosphere, which affects the light.

Im guessing it has something to do with the part where red light has the longest wavelength...
