When you create a spectrum using a glass prism, the edge is straight, meaning you'll get a straight spectrum.
A rainbow is a spectrum made with a raindrop, which is spherical in shape. Therefore when the light reaches the edge of the raindrop it will be refracted in different direction depending on where in the surface of the raindrop it hits, meaning the spectrum will be curved.
