Answer:
decreases
When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law.

Answer:
Speed of light is lower in optically denser medium by definition of refractive index. Refractive index of a medium 1 wrt another medium 2 is defined as:
μ
21
=
v
2
v
1
where:
v
1
; speed of light in medium 1
v
2
: speed of light in medium 2
When, light travels from rarer to denser medium,
μ
21
>1
v
2
<v
1
Hence, speed reduces
