What gives a rainbow its shape?
In raindrops, sunlight bounces back, or reflects, most strongly at a certain angle – 42 degrees. As long as the angle is right, then the light will be reflected and you see a rainbow. So the reflection gives you the shape of the rainbow, while the refraction gives you the colours of the rainbow.
