प्रश्न

In following figure shows two identical prisms A and B placed with their faces parallel to each other. A ray of light of single colour PQ is incident at the face of the prism A. Complete the diagram to show the path of the ray till it emerges out of the prism B.  

 

[Hint: The emergent ray out of the prism B will be parallel to the incident ray PQ] 

थोडक्यात उत्तर

उत्तर

The emerging ray, TU, eventually lies parallel to PQ after bending twice as it passes through prisms A and B, respectively, towards their respective bases.
