Prism Experiment: Seeing a Wide Spectrum of Light?

[Prashasti]

What would happen if two triangular prisms are kept side by side , in the same way?
I mean, none of them is in an inverted position.
Would this arrangement give a wide spectrum of light?

It would change the angles between the different colors relative to just one of those prisms, but you don't get anything special compared to a single prism.
If the light can hit more than one side somewhere, it gets messy.
