1. light that travels from a less - dense to a more - dense medium:

a. loses speed and runs perpendicular to the normal.
b. loses speed and bends toward the normal.
c. increases in speed and runs perpendicular to the normal.
d. increases in speed and bends away from the normal.

Explanation:

When light travels from a less - dense to a more - dense medium, according to the laws of refraction, its speed decreases. Also, the light ray bends towards the normal. This is a fundamental concept in optics related to the change in the medium's optical density.

Answer:

B. loses speed and bends toward the normal
