Lunar eclipse occurs because sunlight toward the moon blocked the earth. Because sunlight leads to the earth, the earth was formed behind the shadow, that is the total dark shadow (umbra) and a dim shadow (penumbra). Total lunar eclipse occurs when the moon is in the umbra region. If the moon is in the penumbra, the eclipse is happening is partly or eclipse lunar eclipse parisal. Lunar eclipse occurs at night time.
Rainbow is formed due to the refraction of sunlight by water droplets in the atmosphere. When sunlight through water droplets, the light is bent in such a way so as to make the colors that exist in the light separately. Each color deflected at different angles, and red is the color most recently bent, while purple is the most first.
