What would the sky look like if we had a blue sun?
If the sun became blue with the same luminosity, the sky would just be bluer. The current blue sky is due to rayleigh scattering, which removes most of the light except blue.
What is facing the sun if you can see a rainbow?
The sun always has to be behind you, though, because the light gets refracted back in the general direction it came from. You’ll never see a rainbow when you’re facing the sun.
Can there be a blue sun?
What if we had a blue sun? Though the sun may appear yellow or reddish to the naked eye, it’s actually an ordinary white star. And the blue version released by NASA was made using a specific wavelength of ultraviolet light known as CaK, which is emitted by ionized calcium in the sun’s atmosphere.
What color would the sky be if the sun was orange?
If the sun were cooler (orange say), the sky might appear as green. That’s because there would be less violet and blue in the sunlight, and the sky color would be shifted to the longer wavelengths.

Why do we see rainbows when it rains?
Water droplets are floating in the air (this is why we see rainbows right after it rains) The sky is clear enough of clouds for the rainbow to be seen. The Role of Raindrops
What type of rainbow appears above a body of water?
A reflection rainbow appears above a body of water. A primary rainbow is reflected by the water, and the reflected light produces a reflection rainbow. Reflection rainbows do not mirror the primary rainbow—they often appear to stretch above it.
What angle does the Sun have to be to see rainbows?
The Sun must be less than 42 degrees above the horizon in order for a rainbow to be seen. A rainbow is unique to each person that sees one, as the sunlight reflected from the raindrops is seen at slightly different angles by each person.
What is the position of the observer during a rainbow?
1 The sun is behind the observer’s position and is no more than 42° above the horizon 2 It’s raining in front of the observer 3 Water droplets are floating in the air (this is why we see rainbows right after it rains) 4 The sky is clear enough of clouds for the rainbow to be seen.
