The diagram above illustrates a beam of parallel rays from a distant object O, incident on one side of the total reflecting prism. Which diagram does not represent the correct path of the beam when it emerges from the prism?
W
X
Y
Z
Correct answer is A
When drawing a ray diagram for instance drawing two rays from the head of the object, the point of intersection of the two rays represents the position of the head of the image, but in the case of parallel rays of light drawn from the object such that the image is likewise formed at infinity, the ray from the head of the object forms the head of the image, similarly, the ray from the leg of the image. from the diagrams drawn, it is only in W that the ray from the head forms the leg of the image, others are correctly drawn.
