Without getting too complicated, the "more dense medium"'s gravitational pull alters the path of the light.
The ray of light will bend away from the normal.
no, towards it
From 1 medium to the other means that light would travel from one object to another. So, it is basically any object that the light passes through.
it deviates its path and meet where water and air surfaces meet.
If the light is at an angle to the medium, then refraction (change of direction) and possibly reflection. If light travels at 90 degrees than maybe only slight reflection.

the waves energy passes from particle to particle

If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
The speed at which a wave passes through water or other medium is called phase velocity.
refraction
it changes in velocity
