Why is the sky blue? Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere Blue is scattered more than other colors because it travels as shorter, smaller waves This is why we see a blue sky most of the time The next one is How do rainbows form? A rainbow is a phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky It takes the form of multi-colored circular arc Rainbows caused by sunlight always appear in the section of light of sky directly opposite the sun and lastly, Why is the sky red when it's sunset? As the sun gets lower in the sky, its light is passing through more of the atmosphere to reach you Even more of the blue light is scattered, allowing the reds and yellows to pass straight through your eyes The next clip I'm gonna show is the video of how this happens
