. A student sets the cross-hairs of an eyepiece in line with an image that he is measuring. He then notes that when he moves his head slightly to the right, the image moves slightly to the left (with respect to the cross-hairs). Therefore the image is:
Options:
Answer:
C
Solution:
By parallax: when the head moves right, the nearer mark appears to move left against the farther one. The image moving left with respect to the cross-hairs means the image is nearer to him than the cross-hairs. Hence (C).
