(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

ABCD represents a square glass block. An object O is placed near the face AB as shown. When observed from the face AD, the object will

(a) appear midway between A and B

(b) appear nearer to A

(c) appear nearer to D

(d) not be seen at all

The answer key tells me that the answer is (d) but I don't know how to prove it.

2. Relevant equations

[itex]\frac{sin\ i}{sin\ r}=\frac{n_2}{n_1}[/itex]

3. The attempt at a solution

I was trying to show that all the rays of light from O to AD are parallel or convergent (real image) but was unsuccessful.
