There will be no spectrum,but only the original light with no deviation

Vedclass · Answer

(C) The correct answer is $C$. When a beam of white light passes through the first prism,it undergoes dispersion and splits into its constituent colors (spectrum). When a second identical prism is placed in an inverted position in contact with the first,it acts as a recombination prism. The dispersion caused by the first prism is exactly cancelled by the second prism,resulting in the recombination of the colors back into a single beam of white light. Since the two prisms together form a structure equivalent to a glass slab with parallel faces,the emergent white light beam is parallel to the incident beam,meaning there is no angular deviation. Therefore,no spectrum is observed on the screen,only the original white light.

White light is split into a spectrum by a prism and it is seen on a screen. If we put another identical inverted prism behind it in contact,what will be seen on the screen?
