The cause for the arched shape of rainbows:
Sunlight that pass through raindrops forms rainbows in a process called refraction, which is bending of light as it passes from one medium to a different medium. The passing of sunlight through raindrop is slower than the passing of sunlight through air, and as a result, a phenomenon of bending of the light occurs (inside the raindrops), after which the light exits the raindrops and continues moving at its previous air-moving speed. When light hits raindrop at a certain angle, the light is refracted to viewers' eyes, and they see a rainbos.
