Answer:
1. diamond is denser as the speed of light is the slowest in it.
2. ice is rarer as the speed of light is fastest in it.
3. the light source refraction when it passes from glass to water as it passes from denser to rarer medium.
4. light slows down when it passes from ice to diamond as it passes from rarer to denser medium and its speed changes according to the medium.
