2.2. When light enters the glass block at A, it is moving from a less dense medium to a denser medium. Hence, the ray of light will bend towards the normal.

2.3. When the ray of light exits the glass block at B, it is moving from a denser medium to a less dense medium. Hence, it will bend away from the normal.
