Draw an arrow to show how visible light might interact when it passes from air to a diamond. Specifically show a refracted light ray as it would interact with
the diamond.

When light enters a diamond, it is refracted out through most of the adjacent and opposite faces of the diamond, after undergoing total internal reflections at some faces

Explanation:

The sketched image below shows how light that impinges from air into the diamond through surface A is refracted towards surface B. At surface B, the light is reflected internally and travels to surface C through which it is refracted as it enters back into the air.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

wavelength divides in half and speed stays the same.
