How will you use two identical prisms so that a narrow beam of white light incident on one prism emerges out of the second prism as white light? Draw the diagram.

Consider a prism A. When white light falls on it, it splits into seven constituent colours. The violet colour deviates the most and red colour deviates the least, as shown.
If another prism B is placed such that they are as shown below, the light that emerges out of A will be made to merge together to come out as white light.
