When a ray of light passes from a denser to a rarer medium:
✓
Answer
- It bends away from the normal.
When a ray of light passes from a denser to a rarer medium, some part of it gets refracted into the rarer medium such that it bends away from the normal. Some part of it gets reflected back into the denser medium. The light reflected back into the denser medium is said to be internally reflected.
