Ray Optics and Optical Instruments

Solution:

In the figure, the path shown for the ray $2$ is correct. The ray suffers two refractions : At $A$, ray goes from air to turpentine, bending towards normal. At $B$, ray goes from turpentine to water (i.e., from denser to rarer medium), bending away from normal.
