WebIndeed your completely correct as when light ray travels from a less dense medium into a denser medium, velocity of the light way changes (velocity is a vector quantity so both direction and speed will change). When you enter a denser medium, speed of light ray slows down and hence the refracted ray bends towards the normal.
