When light travels from a denser medium to a rarer medium, it bends away from the normal, not towards it. Hence, option 3 is false.

Refraction is the bending of the path of a light wave as it passes from one media to another media.
 It is caused by the change in speed experienced by the light ray. 
When a ray of light travels from a denser medium to a rarer medium, the ray will speed up and bend away from the normal.

The incident ray, the refracted ray and the normal to the interface all lie in the same plane.

When light travels from air (vacuum with velocity c) to a medium with velocity v, then refractive index of the medium can be written as u = c/v.

When light travels from a denser medium to rarer medium, it bends towards the normal.

The ratio of sine of incidence angle (i) to the sine of refracted angle (r) is a constant for that pair of media.
