How does density affect refraction?

Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

Explain where you observe reflection, refraction, and absorption of light in your everyday activities.

Optically denser object usually has a higher refractive index. A higher refractive index causes light to refract more and total internal refraction is easier to occur. Direct a light in to the diamond and the light is first refracted into the diamond, and then total internal refraction reflects the light back out and into our eyes.
