If you were looking for a rainbow after a rainstorm would you look at the direction of the sun or the opposite from the sun?

You would look opposite the direction of the sun to find a rainbow after a rainstorm. Rainbows form when sunlight refracts, reflects, and disperses in water droplets, and this process requires the sun to be behind you. The arc of the rainbow will appear in the part of the sky that is away from the sun.
