Question
Light travelling from air to which of the following mediums bends away from the normal?
- Diamond
- Sapphire
- Ruby
- None of these
Hint:
When moving from a rarer to a denser medium, a light ray bends away from the normal.
The correct answer is: None of these
Light travelling from air to none of the following mediums bends away from the normal.
- The light ray bends away from the normal when it passes from air into a less dense medium.
- The diamond, sapphire, and ruby are more dense mediums comparatively.
- So none of these mediums cause bending of the refracted ray away from the normal.
- Thus, the light ray that passes from air into the mediums like diamond, sapphire, and ruby bends away from the normal.
