Light bends away from normal when it passes from denser to rarer medium. why?

The everyday is a line perpendicular (forming a 90 degree attitude) to the boundary between the two materials. The bending takes place because mild travels more slowly in a denser medium. an indication of refraction can be conducted at home in a dark room.
