Question
State four differences between reflection and total internal reflection.
✓
Answer
| S. No | Reflection | Total Internal Reflection |
| 1. | Smooth polished surface is required for reflection. | No smooth, polished surface is required for total internal relflection. |
| 2. | It takes place for all the angles of incidence. | It takes place when the rays strike at an angle greater than the critical angle. |
| 3. | It takes place when the rays of light is incident on a plane mirror from any medium at any angle of incidence. | It takes place when the rays of light travel from a denser to a rarer medium. |
| 4. | Some rays of light are absorbed by the reflecting material. | No rays of light are absorbed. |
