If it's zero, i.e. the ray falls perpendicular to the glass slab, sin i is zero. And according to Snell's law sin r is also zero, i.e. the refraction angle r measured from normal is zero. Therefore, the ray is undeviated.

Explanation:

Because when light passes through a glass slab it emerges parallel to the incident ray and is shifted from the original path.
